We demonstrate trapping and characterization of multiple gold nanospheres with a setup composed of dark field imaging and optical tweezers. The number of trapped nanospheres is quantified by the overall dark-field scattering intensity. The spectra of the scattering intensity show that there is no interparticle coupling among trapped nanospheres when the density of nanospheres in the trap is low enough (less than 10 particles), while the density of nanosphere increases the interparticle coupling of nanospheres becomes obvious. In addition, the trapping potential of a single gold nanosphere is obtained by trapping an ensemble of gold nanospheres.. ©2013 Optical Society of America. Full Article , PDF Article ...
Gold nanoparticles have attracted enormous interest as potential theranostic agents. However, little is known about the long-term elimination and systemic toxicity of gold nanoparticles in the literature. Hollow gold nanospheres (HAuNS) is a class of photothermal conducting agent that have shown promises in photoacoustic imaging, photothermal ablation therapy, and drug delivery. Its very necessary to make clear the biosafety of HAuNS for its further application. We investigated the cytotoxicity, complement activation, and platelet aggregation of polyethylene glycol (PEG)-coated HAuNS (PEG-HAuNS, average diameter of 63 nm) in vitro and their pharmacokinetics, biodistribution, organ elimination, hematology, clinical chemistry, acute toxicity, and chronic toxicity in mice. PEG-HAuNS did not induce detectable activation of the complement system and did not induce detectable platelet aggregation. The blood half-life of PEG-HAuNS in mice was 8.19 ± 1.4 hr. The single effective dose of PEG-HAuNS in

Highly porous nano carbon materials have been widely developed due to their advanced physical characteristics such as morphology, light weight, but more interestingly the possibility of designing the level of porosity as well as the specific surface area with many different approaches. This shows great potential in gas adsorption, separation, environmental treatment, energy storage and conversion, etc. Based on these properties, we investigated the synthesis of porous carbon nanosphere via two-steps process, using phenolic resol as a carbon source and block copolymer F127 as a soft template via hydrothermal process followed by graphitization. The porous nanospheres have high surface area of 1099 m2/g after KOH activation measured by nitrogen sorption isotherms. Furthermore, the surface chemistry was characterized by elemental analysis, infrared spectroscopy and x-ray photoelectron spectroscopy. The uniformity in the size of the nanospheres was verified by SEM and TEM analyses. The nanospheres show H2
We present a comparative study of the toxicity of polyethylene glycol (PEG)-coated cobalt ferrite nanoparticles and nanospheres. Nanoparticles were prepared by hydrothermal method while nanospheres were prepared by solvothermal technique. The surface of nanomaterials was successfully modified with polyethylene glycol. To investigate the morphology of the prepared samples, X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, thermogravimetric analysis (TGA), and electron microscopy techniques were employed. Structural analyses confirmed the formation of polycrystalline cobalt ferrite nanoparticles with diameters in the range 20-25 nm and nanospheres in the range 80-100 nm, respectively. Kunming SPF mice (female, 6-8 weeks old) were used to investigate the toxicity induced by cobalt ferrite nanoparticles and nanospheres in different organs of the mice. Biodistribution studies, biochemical indices, histopathological assessments, inflammatory factors, oxidation and

PY - 2004/1/1. Y1 - 2004/1/1. N2 - Macroscopic regular stripe-crack patterns have been observed in the course of drying the aqueous suspensions of ammonium-modified polymer nanospheres. These forms emerged because the evaporation of dispersed water and self-assembly of nanospheres originates shrinkage during drying the aqueous suspensions. The drying condition plays an important role as well as the nature of the ammonium-modified polymer nanospheres for the stripe-crack pattern formation. By means of the vertical deposition method, directional stripe-crack patterns have been achieved in the macroscopic scale. Surprisingly, we have still noted an interesting secondary stripe pattern occurred spontaneously on the stripes..

Nanoparticulate MR contrast agents are much more effective owing to their enhanced relaxivity, a result of reduced tumbling rates, and large payloads of active magnetic species. PEGylated yolk-shell silica nanospheres containing high payloads of Gd(iii) with cross-linking ligands are synthesized and evaluated as a blood-pool magnetic resonance contrast agent. The hydrophilic PEG coating and the microporous silica shell allow water exchange while keeping the multi-nuclear Gd species from leaching out.

Fabrication of monodisperse pure silica and core-shell nanospheres ([email protected] and Fe2O3/[email protected]) was done in straight forward one-pot method combining sol-gel chemistry and supercritical fluids. For the core-shell materials, preformed nanoparticles stabilized in hexane were dispersed in a sol containing a silicon alkoxide, water and acetone as the solvent. The precursor solution was introduced in an autoclave and pressurized with compressed CO2. Then, pressure and temperature were raised over the supercritical conditions of the CO2/acetone mixture allowing the silicon alkoxide to hydrolyze and condensate forming the silica shell. The composite gel nanospheres got dried as the solvent was extracted at supercritical conditions. They present a narrow particle size distribution (with less than 30% polidispersity). Each nanosphere consists of a functional core of several non-contacting γFe2O3 nanoparticles and/or quantum dots surrounded by a microporous silica shell. Their size can be tuned by controlling
Nanosphere lithography, an inexpensive and high throughput technique capable of producing nanostructure (below 100 nm feature size) arrays, relies on the formation of a monolayer of self-assembled nanospheres, followed by custom-etching to produce nanometre size features on large-area substrates. A theoretical model underpinning the self-ordering process by centrifugation is proposed to describe the interplay between the spin speed and solution concentration. The model describes the deposition of a dense and uniform monolayer by the implicit contribution of gravity, centrifugal force and surface tension, which can be accounted for using only the spin speed and the solid/liquid volume ratio. We demonstrate that the spin recipe for the monolayer formation can be represented as a pathway on a 2D phase plane. The model accounts for the ratio of polystyrene nanospheres (300 nm), water, methanol and surfactant in the solution, crucial for large area uniform and periodic monolayer deposition. The ...

Uniform-sized silica nanospheres with a well-ordered arrangement were successfully synthesized by a novel and simple method; hydrolysis and condensation reactions of tetraethyl orthosilicate were conducted in the presence of basic amino acids.
A one-step method to prepare core-shell nanoparticles and thus hollow nanospheres is reported. The process for the formation of core and shell took place during reaction. Once the core formed, it was covered with the shell substance produced in situ, and thus, the shell hindered the continued growth of the core. Based on this method, we readily obtained core-shell nanoparticles by choosing AgCl, CuS, or Fe(III) diethyldithiocarbamate (FeDEC)3 as model core substances and the cogel from gelatin and gum arabic as the shell substance. High-resolution transmission electron microscopy (HRTEM) directly revealed the core-shell structure. TEM results showed the average particle sizes were under 100 nm, depending on the core substance and the concentration of substances producing cores. After removal of the core materials, hollow nanospheres resulted, which were directly observed by TEM. The observation further verified the core-shell structure. UV spectrophotometry also gave signals of coated structure ...
Since energy economy and environmental safety are of major concern currently, here we report a simple, greener, template-free synthesis route to prepare tin oxide (SnO2) hollow and solid core nanospheres. The formation and growth mechanisms of such tin oxide nanospheres with solid and hollow cores having sizes of 50 nm-200 nm have been elucidated for the first time in this report. The electrochemistry of such hollow and solid spheres has been investigated against Li/Li+. Tin oxide (without an in situ conductive carbon coating) with a hollow core anode morphology exhibits an outstanding energy density of similar to 600 mA h g(-1) at a current density of 178 mA g(-1). Our electrochemical results and the discussion about hollow and solid core formation mechanisms, indicate the importance of our work and the electrochemical properties indicate that they could be used as anodes for lithium-ion batteries ...
Due to the increased prevalence of resistant bacterial isolates which are no longer susceptible to antibiotic treatment, recent emphasis has been placed on finding alternative modes of treatment of wound infections. Bacteriophage have long been investigated for their antimicrobial properties, yet the utilization of phage therapy for the treatment of wound infections relies on a suitable delivery system. Poly(N-isopropylacrylamide) (PNIPAM) is a thermally responsive polymer which undergoes a temperature dependent phase transition at a critical solution temperature. Bacteriophage K has been successfully formulated with PNIPAM nanospheres copolymerized with allylamine (PNIPAM-co-ALA). By utilizing a temperature responsive polymer it has been possible to engineer the nanospheres to collapse at an elevated temperature associated with a bacterial skin infection. The nanogels were reacted with surface deposited maleic anhydride in order to anchor the nanogels to non-woven fabric. Bacteriophage ...
Fargo, N.D. - A patent-pending technology to produce nanospheres developed by a research team at North Dakota State University, Fargo, could enable advances across multiple industries, including electronics, manufacturing, and biomedical sectors. The environmentally-friendly process produces polymer-based nanospheres (tiny microscopic particles) that are uniform in size and shape, while being low-cost and easily reproducible. The process developed at NDSU allows scale-up of operation to high production levels, without requiring specialized manufacturing equipment. A 3a.m. Eureka! Moment Dr. Victoria Gelling, associate professor in the Department of Coatings and Polymeric Materials at NDSU, had a "Eureka!" moment when she woke early one morning - 3 a.m., to be precise, an hour when most of us are still sleeping. Gelling used early morning creativity to imagine a new way to oxidize monomers, which are relatively small and simple molecules, into polymers, which are larger, more complex molecules ...
We report measurements and theoretical analysis of resonant spin tunneling in randomly oriented nanospheres of a molecular magnet. Amorphous nanospheres of Mn₁₂ acetate have been fabricated and characterized by chemical, infrared, TEM, X-ray, and magnetic methods. Magnetic measurements have revealed sharp tunneling peaks in the field derivative of the magnetization that occur at the typical resonant field values for the Mn₁₂ acetate crystal in the field parallel to the easy axis.Theoretical analysis is provided that explains these observations. We argue that resonant spin tunneling in a molecular magnet can be established in a powder sample, without the need for a single crystal and without aligning the easy magnetization axes of the molecules. This is confirmed by re-analyzing the old data on a powdered sample of non-oriented micron-size crystals of Mn₁₂ acetate. In conclusion, our findings can greatly simplify the selection of candidates for quantum spin tunneling among newly ...

This work addresses a new configuration that improves the sensitivity of a humidity sensor based on a long-period fiber grating coated with a SiO2-nanospheres film. An intermediate higher refractive index overlay, deposited through Electrostatic Self-Assembly, is placed between the fiber cladding and the humidity sensitive film in order to increase the total effective refractive index of the coating. With this intermediate design, a three-fold improvement in the sensitivity was obtained. Wavelength shifts up to 15 nm against 5 nm were achieved in a humidity range from 20% to 80%.

Graphene paper as a new form of graphene-supported nanomaterials has received worldwide attention since its first report in 2007. Due to their high flexibility, lightweight and good electrical conductivity, graphene papers have demonstrated the promising potential for crucial applications in electrochemical sensors and energy technologies among others. In this chapter, we present some examples to overview recent advances in the research and development of two-dimensional (2D) graphene papers as new materials for electrochemical sensors. The chapter covers the design, fabrication, functionalization and application evaluations of graphene papers. We first summarize the mainstream methods for fabrication of graphene papers/membranes, with the focus on chemical vapour deposition techniques and solution-processing assembly approaches. A large portion of this chapter is then devoted to the highlights of specific functionalization of graphene papers with polymer and nanoscale functional building blocks for
The inner-surface functionalization of hollow silica spheres has rarely been reported and is still a challenging topic. Herein, we report a deacetalization-Henry cascade reaction catalyzed by dual-functionalized mesoporous silica hollow nanospheres with basic amine groups ([BOND]NH2) on the internal shell and carboxylic acid groups ([BOND]COOH) on the external shell. The selective functionalization has been realized by a combination of "step-by-step post-grafting" and "cationic surfactant-assisted selective etching" strategy. Compared to unisolated catalyst, the selectively isolated acidic and basic dual catalyst provides excellent catalytic performance for the deacetalization-Henry cascade reaction in terms of both activity (,99 %) and selectivity (95 %).. ...
In this research, self-assembled copper sulfide nanospheres were synthesized by the solvothermal method and the effects of reaction parameters, including reaction time and reaction temperature on the morphology and phase evolution of copper sulfide nanostructures were investigated. For the identification of copper sulfide nanostructures, X-ray diffraction (XRD), infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FE-SEM), and elemental analysis (EDX) were used. The results showed that the temperature of 200 °C for 24 h is sufficient for the formation of the pure hexagonal Cu7.2S4 phase. The Cu7.2S4 nanostructures have a spherical morphology that formed from the self-assembly of the nanoparticles. Finally, the photocatalyst efficiency of Cu7.2S4 sphere was investigated.

Military personnel during combat operations are highly susceptible to traumatic brain and spinal cord injury. There are reasons to believe that a focal injury to the central nervous system (CNS) causes multiple biochemical and pathological changes in the fluid microenvironment in which neurons and glial cells are suspended. This would lead to a process of cascade leading to neurodegenerative diseases e.g., Parkinsons Disease (PD) and/or Alzheimers Diseases (AD). So far no suitable therapeutic strategies are available to reduce or contain the pathophysiology of PD/AD in clinics. Thus, there is an urgent need to explore new therapeutic strategies to reduce pathophysiological consequences of AD/PD. Since Cerebrolsyin (CBL) is a balanced composition of several neurotrophic factors and active peptide fragments, the drug could be more beneficial in treating PD. Thus, in present investigation we examined nanodelivery of CBL using titanate nanospheres in an animal model of PD and evaluated the

Aphios is enhancing the oral bioavailability of therapeutic proteins by encapsulating protein macromolecules and nanoparticles in biodegradable polymer nanospheres," says Dr. Trevor P. Castor, President & CEO, Aphios Corporation. Nanoencapsulation is being used to protect the protein macromolecules/nanoparticles during the stomach passage; the residence time in the stomach will be short compared to the protein release rate from the polymer nanospheres. Animal data demonstrates that insulin, a labile peptide, being nanoencapsulated was protected in the stomach and then transported to the blood. When protein nanoparticles reach the gut, they are transported across the lining, which may be mediated by M cells in the lymphatic tissue of the gut. Alternatively, the protein can be mobilized from nanospheres and rapidly transported to systemic circulation by the epithelial cells. Both the polymer "shell" and the protein macromolecules/nanoparticles are intended to enable and regulate this stage of drug ...
