The refractive index of light reflecting off this surface is measured. When the immobilized biomolecules are bound by their ligands, an alteration in surface plasmons on the opposite side of the film is created which is directly proportional to the change in bound, or adsorbed, mass. Binding is measured by changes in the refractive index. The technique is used to study biomolecular interactions, such as antigen-antibody binding.

Signaling through Raf-1 in the neovasculature and target validation by nanoparticles. (1/2196)

A recent study demonstrated that vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) activate Raf-1 kinase in an experimental neovasculature system. The study showed that bFGF and VEGF activate p21-activated protein kinase-1 (PAK-1) and Src kinase, respectively. PAK-1 and Src kinases phosphorylate specific serine and tyrosine residues within the activation loop of Raf-1 kinase. Their findings further suggest that phosphorylation at these sites protects endothelial cells from apoptosis induced by both intrinsic and extrinsic factors. The tumor neovasculature provides specific molecular markers or "zip codes". This group of investigators has previously shown that nanosphere-aided targeting of the neovasculature with mutant Raf-1 causes regression of the tumor vasculature. Thus, nanoparticles coated with "zip code"-specific homing biomolecules may be useful for delivering anti-angiogenic molecules that can induce tumor regression.  (+info)

Reducing activity of colloidal platinum nanoparticles for hydrogen peroxide, 2,2-diphenyl-1-picrylhydrazyl radical and 2,6-dichlorophenol indophenol. (2/2196)

Shimizu and Tsuji established a method of preparing colloidal platinum nanoparticles, whose average size is 2 nm, by ethanol reduction of H(2)PtCl(6) in the absence of protective agents for the particles. Platinum nanoparticles have negative surface potential and are stably suspended from an electric repulsion between them. The platinum nanoparticles reduced hydrogen peroxide and 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) below 0.1 ppm. It is necessary to use higher concentration of platinum nanoparticles for the reduction of 2,6-dichlorophenol indophenol (DCIP) than that of hydrogen peroxide and 2,2-diphenyl-1-picrylhydrazyl radical, because reoxidation of DCIPH(2) (reduced) by oxygen was not negligible under our experimental conditions. These results indicate that electrons on platinum nanoparticles produced by the method of Shimizu and Tsuji can reduce hydrogen peroxide, DPPH radical or DCIP transferring electrons.  (+info)

Homogeneous detection of unamplified genomic DNA sequences based on colorimetric scatter of gold nanoparticle probes. (3/2196)

Nucleic acid diagnostics is dominated by fluorescence-based assays that use complex and expensive enzyme-based target or signal-amplification procedures. Many clinical diagnostic applications will require simpler, inexpensive assays that can be done in a screening mode. We have developed a 'spot-and-read' colorimetric detection method for identifying nucleic acid sequences based on the distance-dependent optical properties of gold nanoparticles. In this assay, nucleic acid targets are recognized by DNA-modified gold probes, which undergo a color change that is visually detectable when the solutions are spotted onto an illuminated glass waveguide. This scatter-based method enables detection of zeptomole quantities of nucleic acid targets without target or signal amplification when coupled to an improved hybridization method that facilitates probe-target binding in a homogeneous format. In comparison to a previously reported absorbance-based method, this method increases detection sensitivity by over four orders of magnitude. We have applied this method to the rapid detection of mecA in methicillin-resistant Staphylococcus aureus genomic DNA samples.  (+info)

Oligonucleotide-displaced organic monolayer-protected silver nanoparticles and enhanced luminescence of their salted aggregates. (4/2196)

N-(2-mercaptopropionyl)glycine (tiopronin) monolayer-protected silver particles were partially displaced by single-stranded oligonucleotides through ligand exchanges. The oligonucleotide-displaced particles could be hybridized with complementary fluorophore-labeled oligonucleotides. Both the oligonucleotide-displaced and hybridized particles could be aggregated by electrostatic interactions with salt in buffer solution, and the aggregates displayed enhanced luminescence from fluorophores. This result suggests the possible application of surface-enhanced fluorescence from metallic nanoparticle aggregation for DNA detection.  (+info)

Nanostructure of cationic lipid-oligonucleotide complexes. (5/2196)

Complexes (lipoplexes) between cationic liposomes and single-strand oligodeoxynucleotides (ODN) are potential delivery systems for antisense therapy. The nanometer-scale morphology of these assemblies is relevant to their transfection efficiency. In this work the monocationic lipid dioleoyloxytrimethylammoniumpropane, the neutral "helper" lipid cholesterol, and an 18-mer anti-bcl2 ODN were combined at different ratios. The lipoplexes formed were characterized for the quantity of ODN bound, for the degree of lipid mixing, and for their size. The nanostructure of the system was examined by cryogenic-temperature transmission electron microscopy, augmented by small-angle x-ray scattering. Addition of ODN to cationic liposomes induced both liposome aggregation and the formation of a novel condensed lamellar phase. This phase is proposed to be stabilized by anionic single-strand ODN molecules intercalated between cationic bilayers. The proportion of cholesterol present apparently did not affect the nature of lipoplex microstructure, but changed the interlamellar spacing.  (+info)

A nanosensor for transmembrane capture and identification of single nucleic Acid molecules. (6/2196)

We have engineered a nanosensor for sequence-specific detection of single nucleic acid molecules across a lipid bilayer. The sensor is composed of a protein channel nanopore (alpha-hemolysin) housing a DNA probe with an avidin anchor at the 5' end and a nucleotide sequence designed to noncovalently bind a specific single-stranded oligonucleotide at the 3' end. The 3' end of the DNA probe is driven to the opposite side of the pore by an applied electric potential, where it can specifically bind to oligonucleotides. Reversal of the applied potential withdraws the probe from the pore, dissociating it from a bound oligonucleotide. The time required for dissociation of the probe-oligonucleotide duplex under this force yields identifying characteristics of the oligonucleotide. We demonstrate transmembrane detection of individual oligonucleotides, discriminate between molecules differing by a single nucleotide, and investigate the relationship between dissociation time and hybridization energy of the probe and analyte molecules. The detection method presented in this article is a candidate for in vivo single-molecule detection and, through parallelization in a synthetic device, for genotyping and global transcription profiling from small samples.  (+info)

Rapid double 8-nm steps by a kinesin mutant. (7/2196)

The mechanism by which conventional kinesin walks along microtubules is poorly understood, but may involve alternate binding to the microtubule and hydrolysis of ATP by the two heads. Here we report a single amino-acid change that affects stepping by the motor. Under low force or low ATP concentration, the motor moves by successive 8-nm steps in single-motor laser-trap assays, indicating that the mutation does not alter the basic mechanism of kinesin walking. Remarkably, under high force, the mutant motor takes successive 16-nm displacements that can be resolved into rapid double 8-nm steps with a short dwell between steps, followed by a longer dwell. The alternating short and long dwells under high force demonstrate that the motor stepping mechanism is inherently asymmetric, revealing an asymmetric phase in the kinesin walking cycle. Our findings support an asymmetric two-headed walking model for kinesin, with cooperative interactions between the two heads. The sensitivity of the 16-nm displacements to nucleotide and load raises the possibility that ADP release is a force-producing event of the kinesin cycle.  (+info)

Nanometer size diesel exhaust particles are selectively toxic to dopaminergic neurons: the role of microglia, phagocytosis, and NADPH oxidase. (8/2196)

The contributing role of environmental factors to the development of Parkinson's disease has become increasingly evident. We report that mesencephalic neuron-glia cultures treated with diesel exhaust particles (DEP; 0.22 microM) (5-50 microg/ml) resulted in a dose-dependent decrease in dopaminergic (DA) neurons, as determined by DA-uptake assay and tyrosine-hydroxylase immunocytochemistry (ICC). The selective toxicity of DEP for DA neurons was demonstrated by the lack of DEP effect on both GABA uptake and Neu-N immunoreactive cell number. The critical role of microglia was demonstrated by the failure of neuron-enriched cultures to exhibit DEP-induced DA neurotoxicity, where DEP-induced DA neuron death was reinstated with the addition of microglia to neuron-enriched cultures. OX-42 ICC staining of DEP treated neuron-glia cultures revealed changes in microglia morphology indicative of activation. Intracellular reactive oxygen species and superoxide were produced from enriched-microglia cultures in response to DEP. Neuron-glia cultures from NADPH oxidase deficient (PHOX-/-) mice were insensitive to DEP neurotoxicity when compared with control mice (PHOX+/+). Cytochalasin D inhibited DEP-induced superoxide production in enriched-microglia cultures, implying that DEP must be phagocytized by microglia to produce superoxide. Together, these in vitro data indicate that DEP selectively damages DA neurons through the phagocytic activation of microglial NADPH oxidase and consequent oxidative insult.  (+info)

A study of DNA tube formation mechanisms using 4-, 8-, and 12-helix DNA nanostructures<...
TY - JOUR. T1 - A study of DNA tube formation mechanisms using 4-, 8-, and 12-helix DNA nanostructures. AU - Ke, Yonggang. AU - Liu, Yan. AU - Zhang, Junping. AU - Yan, Hao. PY - 2006/4/5. Y1 - 2006/4/5. N2 - This paper describes the design and characterization of a new family of rectangular-shaped DNA nanostructures (DNA tiles) containing 4, 8, and 12 helices. The self-assembled morphologies of the three tiles were also investigated. The motivation for designing this set of DNA nanostructures originated from the desire to produce DNA lattices containing periodic cavities of programmable dimensions and to investigate the mechanism of DNA tube formation. Nine assembly scenarios have been investigated through the combination of the three different tiles and three sticky end association strategies. Imaging by atomic force microscopy (AFM) revealed self-assembled structures with varied cavity sizes, lattice morphologies, and orientations. Six samples show only tube formation, two samples show both ...

Nanopillar - WikipediaNanopillar - Wikipedia
Nanopillars is an emerging technology within the field of nanostructures. Nanopillars are pillar shaped nanostructures approximately 10 nanometers in diameter that can be grouped together in lattice like arrays. They are a type of metamaterial, which means that nanopillars get their attributes from being grouped into artificially designed structures and not their natural properties. Nanopillars set themselves apart from other nanostructures due to their unique shape. Each nanopillar has a pillar shape at the bottom and a tapered pointy end on top. This shape in combination with nanopillars ability to be grouped together exhibits many useful properties. Nanopillars have many applications including efficient solar panels, high resolution analysis, and antibacterial surfaces. Due to their tapered ends, nanopillars are very efficient at capturing light. Solar collector surfaces coated with nanopillars are three times as efficient as nanowire solar cells. Less material is needed to build a solar ...

Molecular self-assembly - WikipediaMolecular self-assembly - Wikipedia
Molecular self-assembly is the process by which molecules adopt a defined arrangement without guidance or management from an outside source. There are two types of self-assembly. These are intramolecular self-assembly and intermolecular self-assembly. Commonly, the term molecular self-assembly refers to intermolecular self-assembly, while the intramolecular analog is more commonly called folding. Molecular self-assembly is a key concept in supramolecular chemistry. This is because assembly of molecules in such systems is directed through noncovalent interactions (e.g., hydrogen bonding, metal coordination, hydrophobic forces, van der Waals forces, π-π interactions, and/or electrostatic) as well as electromagnetic interactions. Common examples include the formation of micelles, vesicles, liquid crystal phases, and Langmuir monolayers by surfactant molecules. Further examples of supramolecular assemblies demonstrate that a variety of different shapes and sizes can be obtained using molecular ...

Innovative optical lactate biosensing through the design of nanostructured materialsInnovative optical lactate biosensing through the design of nanostructured materials
The scope of this thesis is the synthesis of nanostructured materials, their functionalization and use for optical lactate biosensing applications. Rapid detection of L-lactate is important in many applications in the clinical sector, in the food industry, or in biotechnology. The formation of enzyme loaded nanostructured materials is a promising approach to obtain performing, reliable and stable enzyme-based optical biosensors. Two different sensing schemes are proposed: the development of lactate-responsive films (pathches) and the development of a microparticle based lactate detection system. The content of this work can be divided in three main tasks: (i) the synthesis of nanostructured support materials for enzyme immobilization, (ii) the functionalization of these materials towards lactate detection, and (iii) the assessment of the performance and sensitivity of these enzyme-loaded films and particles for biosensor applications. The design of porous supports aims at providing large surface ...

Synthesis of Nanostructures in Chlorine-Containing Media
Modification of carbon nanostructures by different chemical elements opens an opportunity for synthesis of materials of a new generation for different applications. Filling carbon nanotubes with one or other element will allow for conferring different mechanical, electrical, magnetic and other physical and chemical properties on the nanotubes. This work demonstrates a possibility to produce such materials by the new proposed by authors method for synthesis of carbon nanostructures using arc evaporation of materials in liquid medium. The possibility to produce chlorine-filled nanostructures is illustrated by the example of synthesis in chlorine-containing media. The possibility to produce chlorine-filled carbon nanostructures by the arc synthesis of nanostructures in the liquid phase has been demonstrated. The proposed method may be one of the most efficient methods for synthesis of carbon nanostructures.

Cyclodextrin based nanosponges for pharmaceutical use: A review : Acta PharmaceuticaCyclodextrin based nanosponges for pharmaceutical use: A review : Acta Pharmaceutica
Nanosponges are a novel class of hyper-crosslinked polymer based colloidal structures consisting of solid nanoparticles with colloidal sizes and nanosized cavities. These nano-sized colloidal carriers have been recently developed and proposed for drug delivery, since their use can solubilize poorly water-soluble drugs and provide prolonged release as well as improve a drugs bioavailability by modifying the pharmacokinetic parameters of actives. Development of nanosponges as drug delivery systems, with special reference to cyclodextrin based nanosponges, is presented in this article. In the current review, attempts have been made to illustrate the features of cyclodextrin based nanosponges and their applications in pharmaceutical formulations. Special emphasis has been placed on discussing the methods of preparation, characterization techniques and applications of these novel drug delivery carriers for therapeutic purposes. Nanosponges can be referred to as solid porous particles having a ...

Electrical Properties of Double-Sided Polymer Surface Nanostructures | Nanoscale Research Letters | Full TextElectrical Properties of Double-Sided Polymer Surface Nanostructures | Nanoscale Research Letters | Full Text
In this study, double-sided polymer surface nanostructures are fabricated using twice nanoimprint lithography and metal deposition technique. We perform electrical property measurement on these double-sided surface nanostructures. Open-circuit voltage and short-circuit current of the as-prepared samples with double-sided surface nanostructures and conductive electrode are recorded using an oscilloscope with applying different external force. The measurements are carried out at room temperature. We find that the intensity of open-circuit voltage and short-circuit current for the double-sided surface nanostructures depends strongly on the sizes, shapes, and arrangements of nanostructures and pressure force. The strongest electrical property can be observed in the hexagon nanopillar arrays with the diameter of about 400 nm containing sub-50-nm resolution sharp structures at the force of about 40 N. We discuss the physical mechanisms responsible for these interesting research findings. The experimental

Nanosponges Soak Up Toxins Released by Bacterial Infections and VenomNanosponges Soak Up Toxins Released by Bacterial Infections and Venom
The nanosponges look like red blood cells, and therefore serve as red blood cell decoys that collect the toxins. The nanosponges absorb damaging toxins and divert them away from their cellular targets. The nanosponges had a half-life of 40 hours in the researchers experiments in mice. Eventually the liver safely metabolized both the nanosponges and the sequestered toxins, with the liver incurring no discernible damage.. Each nanosponge has a diameter of approximately 85 nanometers and is made of a biocompatible polymer core wrapped in segments of red blood cells membranes.. Zhangs team separates the red blood cells from a small sample of blood using a centrifuge and then puts the cells into a solution that causes them to swell and burst, releasing hemoglobin and leaving RBC skins behind. The skins are then mixed with the ball-shaped nanoparticles until they are coated with a red blood cell membrane.. Just one red blood cell membrane can make thousands of nanosponges, which are 3,000 times ...

In this work, we report the optical and thermal properties of Cu(BTC)·3H2O (BTC = 1,3,5-benzenetricarboxylic acid) and Zn(ADC)·DMSO (ADC = 9,10- anthracenedicarboxylic acid, DMSO = dimethyl sulfoxide) metal-organic frameworks (MOFs) micro/nanopillars. The morphologies of MOFs on surfaces are most in the form of micro/nanopillars that were vertically oriented on the surface. The size and morphology of the pillars depend on the evaporation time, concentration, solvent, substrate, and starting volume of solutions. The crystal structures of the nanopillars and micropillars are the same, confirmed by powder XRD. Zn(ADC)·DMSO pillars have a strong blue fluorescence. Most of ADC in the pillars are in the form of monomers, which is different from ADC in the solid powder.

OSA | Real-time in situ Mueller matrix ellipsometry of GaSb nanopillars: observation of anisotropic local alignmentOSA | Real-time in situ Mueller matrix ellipsometry of GaSb nanopillars: observation of anisotropic local alignment
The formation of GaSb nanopillars by low energy ion sputtering is studied in real-time by spectroscopic Mueller matrix ellipsometry, from the initial formation in the smooth substrate until nanopillars with a height of 200 - 300 nm are formed. As the nanopillar height increased above 100 nm, coupling between orthogonal polarization modes was observed. Ex situ angle resolved Mueller polarimetry measurements revealed a 180° azimuth rotation symmetry in the off-diagonal Mueller elements, which can be explained by a biaxial material with different dielectric functions εx and εy in a plane parallel to the substrate. This polarization coupling can be caused by a tendency for local direction dependent alignment of the pillars, and such a tendency is confirmed by scanning electron microscopy. Such observations have not been made for GaSb nanopillars shorter than 100 nm, which have optical properties that can be modeled as a uniaxial effective medium.. ©2011 Optical Society of America.

The tantalizing prospect of harnessing the unique properties of graphene crumpled nanostructures continues to fuel tremendous interest in energy storage and harvesting applications. However, the paper ball-like, hard texture, and closed-sphere morphology of current 3D graphitic nanostructure production not only constricts the conductive pathways but also limits the accessible surface area. Here, we report new insights into electrohydrodynamically-generated droplets as colloidal nanoreactors in that the stimuli-responsive nature of reduced graphene oxide can lead to the formation of crumpled nanostructures with a combination of open structures and doubly curved, saddle-shaped edges. In particular, the crumpled nanostructures dynamically adapt to non-spherical, polyhedral shapes under continuous deposition, ultimately assembling into foam-like microstructures with a highly accessible surface area and spatially interconnected transport pathways. The implementation of such crumpled nanostructures as three

Tunable high aspect ratio polymer nanostructures for cell interfaces
Nanoscale topographies and chemical patterns can be used as synthetic cell interfaces with a range of applications including study and control of cellular processes. Herein, we describe the fabrication of high aspect ratio nanostructures using electron beam lithography in the epoxy-based polymer SU-8. We show how nanostructure geometry, position and fluorescent properties can be tuned, allowing flexible device design. Further, thiol-epoxide reactions were developed to give effective and specific modification of SU-8 surface chemistry. SU-8 nanostructures were made directly on glass cover slips, enabling the use of high resolution optical techniques such as live-cell confocal, total internal reflection and 3D structured illumination microscopy to investigate cell interactions with the nanostructures. Details of cell adherence and spreading, plasma membrane conformation and actin organization in response to high aspect ratio nanopillars and nanolines were investigated.

Converging peptide- and DNA-nanotechnology: molecular self-assembly of peptide nucleic acidsConverging peptide- and DNA-nanotechnology: molecular self-assembly of peptide nucleic acids
Biology serves as a major inspiration for the assembly of ordered structures at the nanoscale. Two main directions for the development of bio-inspired nanomaterials are based either on the use of protein and peptide building blocks or, alternatively, on the use of DNA. Polypeptide structures have the advantage of structural integrity and robustness while nucleic acids have the advantage of specific molecular recognition between complementary bases.. Our group has been extensively involved in the study of molecular self-assembly by extremely short peptide fragments. We demonstrated in 2003 that simple dipeptides contain all the molecular information needed to form ordered nanostructures [1]. Furthermore, peptide assemblies have been shown to exhibit remarkable physical properties including high mechanical rigidity, luminescence, piezoelectricity, and semiconductivity [2]. The dipeptide assemblies act as supramolecular polymers including a clear phase transition governed by Ostwalds rule of ...

JRC Publications Repository: Development of a Potentiometric Biosensor Based on Nanostructured Surface for Lactate DeterminationJRC Publications Repository: Development of a Potentiometric Biosensor Based on Nanostructured Surface for Lactate Determination
Nanostructuring surfaces in order to improve the quality of determinations, in terms of detection limit and signal-to-noise ratio, had received a great attention in the last years. At this effect, a potentiometric for the determination of lactate, based on a nanostructured (ND) Si4N3 surface, is presented here. The potentiometric sensor developed is an electrolyte¿membrane¿insulator¿semiconductor (EMIS). The surface was first modified by a polyacrylic acid (PAA) layer, deposited by plasma enhanced chemical vapor deposition (PECVD), that can covalently link to the NH2 groups of the lactate dehydrogenase. Secondly, the nanostructures were formed on the surface by colloidal lithography. The obtained nanostructured surface was characterized. The stability of the biosensor in aqueous media was investigated obtaining a sensitivity of 49.7mV per decade. The detection limit for the determination of lactate was 2×10-7 M, with a linear range up to 10-5 M. The intra- and inter-electrode standard ...

Nanostructured materials are promising compounds that offer new opportunities as sensing platforms for the detection of biomolecules. Having micrometer-scale length and nanometer-scale diameters, nanomaterials can be manipulated with current nanofabrication methods, as well as self-assembly techniques, to fabricate nanoscale bio-sensing devices. Nanostructured materials possess extraordinary physical, mechanical, electrical, thermal and multifunctional properties. Such unique properties advocate their use as biomimetic membranes to immobilize and modify biomolecules on the surface of nanoparticles. Alignment, uniform dispersion, selective growth and diameter control are general parameters which play critical roles in the successful integration of nanostructures for the fabrication of bioelectronic sensing devices.

But most of the current fabrication processes require high temperature, which causes problems like long cycle time, non-cost effective and substrate melting temperature restriction. Therefore developing low temperature synthesis of carbon nanostructures is of great scientific and practical significance. This report focuses on the low temperature fabrication and characterization of carbon nanostructures such as onion-like carbon and carbon nanotubes (CNTs).

Discovering new anticancer drugs and screening their efficacy requires a huge amount of resources and time-consuming processes. The development of fast, sensitive, and nondestructive methods for the in vitro and in vivo detection of anticancer drugs effects and action mechanisms have been done to reduce the time and resources required to discover new anticancer drugs. For the in vitro and in vivo detection of the efficiency, distribution, and action mechanism of anticancer drugs, the applications of electrochemical techniques such as electrochemical cell chips and optical techniques such as surface-enhanced Raman spectroscopy (SERS) have been developed based on the nanostructured surface. Research focused on electrochemical cell chips and the SERS technique have been reviewed here; electrochemical cell chips based on nanostructured surfaces have been developed for the in vitro detection of cell viability and the evaluation of the effects of anticancer drugs, which showed the high capability to evaluate

Universidade do Minho: Edible bio-based nanostructures: delivery, absorption and potential toxicityUniversidade do Minho: Edible bio-based nanostructures: delivery, absorption and potential toxicity
The development of bio-based nanostructures as nanocarriers of bioactive compounds to specific body sites has been presented as a hot topic in food, pharmaceutical and nanotechnology fields. Food and pharmaceutical industries seek to explore the huge potential of these nanostructures, once they can be entirely composed of biocompatible and non-toxic materials. At the same time, they allow the incorporation of lipophilic and hydrophilic bioactive compounds protecting them against degradation, maintaining its active and functional performance. Nevertheless, the physicochemical properties of such structures (e.g., size and charge) could change significantly their behavior in the gastrointestinal (GI) tract. The main challenges in the development of these nanostructures are the proper characterization and understanding of the processes occurring at their surface, when in contact with living systems. This is crucial to understand their delivery and absorption behavior as well as to recognize ...

Opto-mechanical coupling effects on metallic nanostructuresOpto-mechanical coupling effects on metallic nanostructures
Surface plasmon is the quantized collective oscillation of the free electron gas in a metallic material. By coupling surface plasmons with photons in different nanostructures, researchers have found surface plasmon polaritons (SPP) and localized surface plasmon resonance (LSPR), which are widely adopted in biosensing, single molecule sensing and detection via surface enhanced raman scattering (SERS), photothermal ablation treatments for cancer, optical tagging and detection, strain sensing, metamaterials, and other applications. The overall objective of this dissertation is to investigate both how mechanics impacts the optical properties, and also how optics impacts the mechanical properties of metal nanostructures reversely. Mechanically engineering individual nanostructures(forward coupling) offers the freedom to alter the optical properties with more flexibility and tunability. It is shown that elastic strain can be applied to gold nanowires to reduce the intrinsic losses for subwavelength ...

The nanostructures were tapered and close-packed, with heights in the range 300-600 nm, and a lateral, spatial frequency in the range 5-7 mu m(-1). A reflectance in the visible spectrum as low as 6%, and an absorbance of 90% was observed for an Al film of 100 nm thickness. Corresponding experiments on a planar film yielded 80% reflectance and 20% absorbance. The observed absorbance enhancement is attributed to a gradient effect causing the metal film to be antireflective, analogous to ...

Complex nanostructures in PMMA made by a single process step using e-beam lithographyComplex nanostructures in PMMA made by a single process step using e-beam lithography
We present results on the single step fabrication of autocentered nanopillars with surrounding circular rim. This particular 3-dimensional shape is created by the energy density distribution of incident and backscattered electrons and reflects the dual behavior of PMMA as positive and negative e-beam resist. Structures with 80 nm rim diameter and 20 nm wide nanopillars could be realized.

On-surface synthesis of organic nanostructures
The project concerns the study of organic nanostructures formed though on-surface synthesis. On-surface synthesis is becoming an increasingly popular approach for creating atomically precise organic nanostructures, through the coupling of molecular building blocks on surfaces, with great relevance and prospects in for example organic electronics. However, very little is known about the on-surface reactions, which makes them arduous to control. Fundamental understanding of the underlying on-surface reactions is therefore of great interest. Furthermore, knowledge is needed for how the structures of the formed materials govern their electronic properties and how the electronic properties of the materials are affected by defects. Such understanding would guide the development of materials with specific electronic properties. The proposed project is divided into two parts. In the first part of the project we will investigate the formation mechanisms of organic nanostructures from molecular building ...

Catalytic Reductive Degradation of Methyl Orange Using Air Resilient Copper NanostructuresCatalytic Reductive Degradation of Methyl Orange Using Air Resilient Copper Nanostructures
The study describes the application of oxidation resistant copper nanostructures as an efficient heterogeneous catalyst for the treatment of organic dye containing waste waters. Copper nanostructures were synthesized in an aqueous environment using modified surfactant assisted chemical reduction route. The synthesized nanostructures have been characterized by UV-Vis, Fourier transform infrared spectroscopy FTIR spectroscopy, Atomic force microscopy (AFM), Scanning Electron Microscopy (SEM), and X-ray diffractometry (XRD). These surfactant capped Cu nanostructures have been used as a heterogeneous catalyst for the comparative reductive degradation of methyl orange (MO) in the presence of sodium borohydride (NaBH|sub|4|/sub|) used as a potential reductant. Copper nanoparticles (Cu NPs) were found to be more efficient compared to copper nanorods (Cu NRds) with the degradation reaction obeying pseudofirst order reaction kinetics. Shape dependent catalytic efficiency was further evaluated from activation

Porous NiTiO3/TiO2 nanostructures for photocatatalytic hydrogen evolutionPorous NiTiO3/TiO2 nanostructures for photocatatalytic hydrogen evolution
We present a strategy to produce porous NiTiO3/TiO2 nanostructures with excellent photocatalytic activity toward hydrogen generation. In a first step, nickel-doped TiO2 needle bundles were synthesized by a hydrothermal procedure. Through the sintering in air of these nanostructures, porous NiTiO3/TiO2 heterostructured rods were obtained. Alternatively, the annealing in argon of the nickel-doped TiO2 needle bundles resulted in NiOx/TiO2 elongated nanostructures. Porous NiTiO3/TiO2 structures were tested for hydrogen evolution in the presence of ethanol. Such porous heterostructures exhibited superior photocatalytic activity toward hydrogen generation, with hydrogen production rates up to 11.5 mmol h-1 g-1 at room temperature. This excellent performance is related here to the optoelectronic properties and geometric parameters of the material ...

Modern fabrication techniques for nanostructures and photonic componentsModern fabrication techniques for nanostructures and photonic components
As a result of this study, several fabrication methods were developed. One of them utilizes focused ion beam lithography for nanofabrication on multilevel and strongly corrugated surfaces. This process has a great potential for general 3D integration and for micro- and nanofluidics. The same approach enables the fabrication of suspended nanostructures and gives a platform for accurate measurement of material properties and realization of lab-on-a-chip concepts. Another separately developed process is a grayscale lithography that provides a control over the height of patterned features at nanometer scale. It gives an effective way to fabricate miniature diffractive optics components for extreme ultraviolet and soft X-ray radiation. It also allows for new designs and improved performance of photonic grating couplers. Finally, the work shows how atomic layer deposition can be used to tune the operational parameters of photonic components. In particular, the dispersion properties of photonic ...

Nanotechnology has been developed for decades and many interesting optical properties have been demonstrated. However, the major hurdle for the further development of nanotechnology depends on finding economic ways to fabricate such nanostructures in large-scale. Here, we demonstrate how to achieve low-cost fabrication using nanosphere-related techniques, such as Nanosphere Lithography (NSL) and Nanospherical-Lens Lithography (NLL). NSL is a low-cost nano-fabrication technique that has the ability to fabricate nano-triangle arrays that cover a very large area. NLL is a very similar technique that uses polystyrene nanospheres to focus the incoming ultraviolet light and exposure the underlying photoresist (PR) layer. PR hole arrays form after developing. Metal nanodisk arrays can be fabricated following metal evaporation and lifting-off processes. Nanodisk or nano-ellipse arrays with various sizes and aspect ratios are routinely fabricated in our research group. We also demonstrate we can ...

Due to high biocompatibility and tailorable properties, DNA-based nanostructures are widely studied in biosensor and nanomedicine applications. The restriction for using DNA-based nanostructures lie in the purification processes which have low product yield and tedious steps involved. MoS2 nanosheets are chosen to test for its purification efficiency as MoS2 is shown to have discriminating properties between single stranded DNA and double stranded DNA. Adsorption studies of different DNA nanostructures are tested to see the adsorption capacity of MoS2. From the adsorption studies, it has been observed that MoS2 has high affinity to plasmid DNA, so the use of MoS2 as a gene carrier is tested for its delivery performance ...

Nanotechnology - Nanofabrication: Two very different paths are pursued. One is a top-down strategy of miniaturizing current technologies, while the other is a bottom-up strategy of building ever-more-complex molecular devices atom by atom. Top-down approaches are good for producing structures with long-range order and for making macroscopic connections, while bottom-up approaches are best suited for assembly and establishing short-range order at nanoscale dimensions. The integration of top-down and bottom-up techniques is expected to eventually provide the best combination of tools for nanofabrication. Nanotechnology requires new tools for fabrication and measurement. The most common top-down approach to fabrication involves lithographic patterning techniques using short-wavelength

Nanostructured lipid carriers (NLC) are stable colloidal formulations with notable advantages for drug delivery systems. Thanks to their physicochemical stability, biocompatibility, biodegradability and controlled drug release, they have received increasing attention for the last several years. The aim of the study was to prepare and characterize nanostructured lipid carriers (NLC). Both, the effect of the process parameters and the effect of the preemulsion composition on the NLC properties were investigated. In the work, different type of surfactants (i.e. decyl glucoside, Poloxamer188, Tween 80, sodium cholate) and their combinations were used to stabilize NLC dispersions. Moreover, several kinds of solid lipids (modified beeswax, gliceryl behenate, cetyl palmitate and berry wax) and liquid lipids (caprilic/capric triglyceride and decyl oleate) were applied. An ultrasonication method using a probe type sonicator was used to obtain NLC, and the time and energy of the process were modified ...

Increasing interest in commercializing functional nanostructured devices heightened the need for cost effective scale-up manufacturing approaches for nanostructures. Diamond turning using multi-tip single crystal diamond tools is a new promising approach to the fabrication of micro/nano structures. In this paper, a serial of nanometric face cutting trails on copper using multi-tip nanoscale diamond tools has been carried out to indentify the nanomanufacturing capacity of this technique under different cutting conditions. The dependency between processing parameters and the surface integrity of the machined nanostructures are discussed. Moreover, large scale molecular dynamics (MD) nanometric cutting model is developed to simulate the nanostructures generation process. The simulation results well reveals the material removal mechanism and explains why structure defects are more likely to be formed in the cases of large depth of cut and high cutting speed observed in experiments.. ...

Optical characterization of anisotropic multicomponent nanostructures is generally not a trivial task, since the relation between a materials structural properties and its permittivity tensor is nonlinear. In this regard, an array of slanted cobalt nanopillars that are conformally coated with few-layer graphene is a particularly challenging object for optical characterization, as it has a complex anisotropic geometry and comprises several materials with different topologies and filling fractions. Normally, a detailed characterization of such complex nanostructures would require a combination of several microscopic and spectroscopic techniques. In this letter, we demonstrate that the important structural parameters of these graphene-coated sculptured thin films can be determined using a fast and simple generalized spectroscopic ellipsometry test combined with an anisotropic Bruggeman effective medium approximation. The graphene coverage as well as structural parameters of nanostructured thin films agree

Small metal nanostructures, especially gold and silver nanoparticles, are known for their interesting optical properties caused by plasmonic effects. Molecular plasmonics, a combination of these optically active nanostructures with the molecular world, opens new possibilities for bioanalytics and (bio-) nanophotonics. Isotropic or anisotropic, homogeneous or heterogeneous metal nanoparticles provide a platform for different, highly defined functional units with interesting optical properties such as plasmon waveguides or molecular beacons. Nanohole arrays in metal layers are another promising component for nanophotonics. New photonic materials were realized from combinations of single metal nanoparticles with individual nanoholes in metals. Atomic force microscopic imaging was used to determine the particle location as well as the lateral dimensions and the topography of the resulting structures. Besides ultramicroscopic characterization of the nanoarrangements, such as nanoparticles positioned ...

Single plasmonic nanostructures for biomedical diagnosis
Abstract. The field of single nanoparticle plasmonics has grown enormously. There is no doubt that a wide diversity of the nanoplasmonic techniques and nanostructures represents a tremendous opportunity for fundamental biomedical studies as well as sensing and imaging applications. Single nanoparticle plasmonic biosensors are efficient in label-free single-molecule detection, as well as in monitoring real-time binding events of even several biomolecules. In the present review, we have discussed the prominent advantages and advances in single particle characterization and synthesis as well as new insight into and information on biomedical diagnosis uniquely obtained using single particle approaches. The approaches include the fundamental studies of nanoplasmonic behavior, two typical methods based on refractive index change and characteristic light intensity change, exciting innovations of synthetic strategies for new plasmonic nanostructures, and practical applications using single particle ...

Electrochemical fabrication of AuCo nanostructures by Maoshi GuanElectrochemical fabrication of AuCo nanostructures by Maoshi Guan
Electrodeposited Au/CoAu multilayered nanowires are materials with alternating layers of Au and CoAu in a wire where the layer thickness and wire diameter are nanometer size. They can be used for different applications. For example, the wires may exhibit giant magnetoresistance (GMR), a change in the materials resistance with a magnetic field, having applications as a sensor material for microdevices. If Co is etched from CoAu nanowires, rough, porous gold nanostructures will be left behind, which could be used as novel catalysts. In this study, the electrodeposition of Au/CoAu multilayered nanowires and nanotubes in nanoporous templates was explored from a non-cyanide electrolyte. The multilayers were deposited with a pulse current control and the template pore size played an important role in determining whether nanowires or nanotubes were formed. The magnetic and magnetoresistive properties of Au/CoAu multilayered nanostructures were examined. Au/CoAu multilayered thin films exhibited both normal and

Field emission from various CuO nanostructures
Three types of CuO nanostructuresâ€the nanorod, nanofiber, and nanoparticleâ€have been grown by using a self-catalytic growth process at 400, 500, and 600 °C, respectively. Field-emission (FE) properties of the CuO nanostructures were investigated. The results indicated that the FE current was significantly affected by the morphologies of the CuO samples. Typical turn-on voltage for the CuO nanofiber array was detected at about 6â€7 V/μm with an emission area of 1 mm[sup 2]. Based on Fowlerâ€Nordheim plot, the values of work function for the nanofiber array were estimated in ranges of 0.56 to 2.62 and 0.30 to 1.39 eV from a two-stage linearity plot. X-ray photoelectron spectroscopy analysis showed no obvious changes in chemical composition of the nanofiber array before and after FE tests. According to the analyses, the highly ordered CuO nanofiber array can be a promising candidate for FE emitters. © 2003 American Institute of Physics ...

OPUS Würzburg | Shadow mask assisted heteroepitaxy of compound semiconductor nanostructuresOPUS Würzburg | Shadow mask assisted heteroepitaxy of compound semiconductor nanostructures
Shadow Mask assisted Molecular Beam Epitaxy (SMMBE) is a technique enabling selected area epitaxy of semiconductor heterostructures through shadow masks. The objective of this work was the development of the SMMBE technique for the reliable fabrication of compound semiconductor nanostructures of high structural and optical quality. In order to accomplish this, technological processes have been developed and optimized. This, in combination with model calculations of the basic kinetic growth processes has enabled the fabrication of high quality quantum structures. A high spatial precision and control of the incidence regions of the molecular beams during the SMMBE process are required for the fabrication of nanostructures. One of the technological developments to this effect, which has substantially enhanced the versatility of SMMBE, is the introduction of a new type of freestanding shadow masks: Growth through such a mask with different incidence angles of the molecular beams is equivalent to employing

Significance of postgrowth processing of ZnO nanostructures on antibacterial activity against gram-positive and gram-negative bacteria Shahid Mehmood,1 Malik A Rehman,1 Hammad Ismail,2 Bushra Mirza,2 Arshad S Bhatti11Center for Micro and Nano Devices, Department of Physics, COMSATS Institute of Information Technology, 2Department of Biochemistry, Faculty of Biological Sciences, Quaid-i-Azam University, Islamabad, PakistanAbstract: In this work, we highlighted the effect of surface modifications of one-dimensional (1D) ZnO nanostructures (NSs) grown by the vaporâ solid mechanism on their antibacterial activity. Two sets of ZnO NSs were modified separately â one set was modified by annealing in an Ar environment, and the second set was modified in O2 plasma. Annealing in Ar below 800°C resulted in a compressed lattice, which was due to removal of Zn interstitials and increased O vacancies. Annealing above 1,000°C caused the formation of a new prominent phase, Zn2SiO4. Plasma oxidation of the

Deoxyribose nucleic acid (DNA) origami nanotechnology is a recently developed self-assembly process for design and fabrication of complex three-dimensional (3D) nanostructures using DNA as a functional material. This paper reviews our recent progress in applying DNA origami to design kinematic mechanisms at the nanometer scale. These nanomechanisms, which we call DNA origami mechanisms (DOM), are made of relatively stiff bundles of double-stranded DNA (dsDNA), which function as rigid links, connected by highly compliant single-stranded DNA (ssDNA) strands, which function as kinematic joints. The design of kinematic joints including revolute, prismatic, cylindrical, universal, and spherical is presented. The steps as well as necessary software or experimental tools for designing DOM with DNA origami links and joints are detailed. To demonstrate the designs, we presented the designs of Bennett four-bar and crank-slider linkages. Finally, a list of technical challenges such as design automation and ...
