Surface Plasmon Resonance
A biosensing technique in which biomolecules capable of binding to specific analytes or ligands are first immobilized on one side of a metallic film.

Direct interaction of lignin and lignin peroxidase from Phanerochaete chrysosporium. (1/3180)

Binding properties of lignin peroxidase (LiP) from the basidiomycete Phanerochaete chrysosporium against a synthetic lignin (dehydrogenated polymerizate, DHP) were studied with a resonant mirror biosensor. Among several ligninolytic enzymes, only LiP specifically binds to DHP. Kinetic analysis revealed that the binding was reversible, and that the dissociation equilibrium constant was 330 microM. The LiP-DHP interaction was controlled by the ionization group with a pKa of 5.3, strongly suggesting that a specific amino acid residue plays a role in lignin binding. A one-electron transfer from DHP to oxidized intermediates LiP compounds I and II (LiPI and LiPII) was characterized by using a stopped-flow technique, showing that binding interactions of DHP with LiPI and LiPII led to saturation kinetics. The dissociation equilibrium constants for LiPI-DHP and LiPII-DHP interactions were calculated to be 350 and 250 microM, and the first-order rate constants for electron transfer from DHP to LiPI and to LiPII were calculated to be 46 and 16 s-1, respectively. These kinetic and spectral studies strongly suggest that LiP is capable of oxidizing lignin directly at the protein surface by a long-range electron transfer process. A close look at the crystal structure suggested that LiP possesses His-239 as a possible lignin-binding site on the surface, which is linked to Asp-238. This Asp residue is hydrogen-bonded to the proximal His-176. This His-Asp...proximal-His motif would be a possible electron transfer route to oxidize polymeric lignin.  (+info)

Absorption of solar radiation by an ellipsoid sensor simulated the human body. (2/3180)

Assessment of heat gain in man caused by solar radiation is one of the most important problems in research of the human heat balance outdoors. The purpose of the present study was to investigate a new method for estimation of solar heat income. Absorption of short wave radiation (direct, diffuse and reflected) was measured with an ellipsoid sensor representing a simple, physical model of man. Measurements were performed in climatic chamber with the use of an iodide CSI solar lamp. The absorbed quantity of solar radiation varied as a result of sun altitude as well as of a colour and insulation of fabric covering the ellipsoid sensor. The new coefficients derived from our investigations for estimating doses of absorbed solar radiation should be applicable for a standing man. They correlate better with mean skin temperature observed on subjects outdoor than previous results obtained based on a cylinder as an analogue model of man. The ellipsoid sensor covered by a black fabric absorbed about 6 times more of solar radiation than when covered by a white textile.  (+info)

T cell receptor and coreceptor CD8 alphaalpha bind peptide-MHC independently and with distinct kinetics. (3/3180)

The T cell surface glycoprotein CD8 enhances T cell antigen recognition by binding to MHC class I molecules. We show that human CD8 alphaalpha binds to the MHC class I molecule HLA-A2 with an extremely low affinity (Kd approximately 0.2 mM at 37 degrees C) and with kinetics that are between 2 and 3 orders of magnitude faster than reported for T cell receptor/peptide-MHC interactions. Furthermore, CD8 alphaalpha had no detectable effect on a T cell receptor (TCR) binding to the same peptide-MHC class I complex. These binding properties provide an explanation as to why the CD8/MHC class I interaction is unable to initiate cell-cell adhesion and how it can enhance TCR recognition without interfering with its specificity.  (+info)

Qualitative and quantitative differences in T cell receptor binding of agonist and antagonist ligands. (4/3180)

The kinetics of interaction between TCR and MHC-peptide show a general relationship between affinity and the biological response, but the reported kinetic differences between antigenic and antagonistic peptides are very small. Here, we show a remarkable difference in the kinetics of TCR interactions with strong agonist ligands at 37 degrees C compared to 25 degrees C. This difference is not seen with antagonist/positive selecting ligands. The interaction at 37 degrees C shows biphasic binding kinetics best described by a model of TCR dimerization. The altered kinetics greatly increase the stability of complexes with agonist ligands, accounting for the large differences in biological response compared to other ligands. Thus, there may be an allosteric, as well as a kinetic, component to the discrimination between agonists and antagonists.  (+info)

Evaluation of relative contributions of two enzymes supposed to metabolise hydrogen peroxide in Paracoccus denitrificans. (5/3180)

A biosensor exploiting an electrochemically mediated enzyme-catalysed reaction was used to quantify relative contributions of cytoplasmic catalase and periplasmic cytochrome c peroxidase to the overall rate of hydrogen peroxide breakdown in cells of Paracoccus denitrificans. The effects of antimycin (an inhibitor of electron flow to cytochrome c peroxidase), the reaction rate versus substrate concentration profiles for the whole cells and subcellular fractions, and the time courses of oxygen concentration demonstrated a profound decrease in the capacity of cytochrome c peroxidase to reduce H2O2 under in vivo conditions. The reason is suggested to be a competition for available electrons between the enzyme and terminal oxidases metabolising oxygen produced by catalase.  (+info)

Sortilin/neurotensin receptor-3 binds and mediates degradation of lipoprotein lipase. (6/3180)

Lipoprotein lipase and the receptor-associated protein (RAP) bind to overlapping sites on the low density lipoprotein receptor-related protein/alpha2-macroglobulin receptor (LRP). We have investigated if lipoprotein lipase interacts with the RAP binding but structurally distinct receptor sortilin/neurotensin receptor-3. We show, by chemical cross-linking and surface plasmon resonance analysis, that soluble sortilin binds lipoprotein lipase with an affinity similar to that of LRP. The binding was inhibited by heparin and RAP and by the newly discovered sortilin ligand neurotensin. In 35S-labeled 3T3-L1 adipocytes treated with the cross-linker dithiobis(succinimidyl propionate), lipoprotein lipase-containing complexes were isolated by anti-sortilin antibodies. To elucidate function in cells, sortilin-negative Chinese hamster ovary cells were transfected with full-length sortilin and shown to express about 8% of the receptors on the cell surface. These cells degraded 125I-labeled lipoprotein lipase much faster than the wild-type cells. The degradation was inhibited by unlabeled lipoprotein lipase, indicating a saturable pathway, and by RAP and heparin. Moreover, inhibition by the weak base chloroquine suggested that degradation occurs in an acidic vesicle compartment. The results demonstrate that sortilin is a multifunctional receptor that binds lipoprotein lipase and, when expressed on the cell surface, mediates its endocytosis and degradation.  (+info)

Sodium dodecyl sulfate stability of HLA-DR1 complexes correlates with burial of hydrophobic residues in pocket 1. (7/3180)

Certain class II MHC-peptide complexes are resistant to SDS-induced dissociation. This property, which has been used as an in vivo as well as an in vitro peptide binding assay, is not understood at the molecular level. Here we have investigated the mechanistic basis of SDS stability of HLA-DR1 complexes by using a biosensor-based assay and SDS-PAGE with a combination of wild-type and mutant HLA-DR1 and variants of hemagglutinin peptide HA306-318. Experiments with wild-type DR1 along with previously published results establish that the SDS-stable complexes are formed only when the hydrophobic pocket 1 (P1) is occupied by a bulky aromatic (Trp, Phe, Tyr) or an aliphatic residue (Met, Ile, Val, Leu). To further explore whether the SDS sensitivity is primarily due to the exposed hydrophobic regions, we mutated residue beta Gly86 at the bottom of P1 to tyrosine, presumably reducing the depth of the pocket and the exposure of hydrophobic residues and increasing the contacts between subunits. In direct contrast to wild-type DR1, the peptide-free mutant DR1 exists as an alpha/beta heterodimer in SDS. Moreover, the presence of a smaller hydrophobic residue, such as alanine, as P1 anchor with no contribution from any other anchor is sufficient to enhance the SDS stability of the mutant complexes, demonstrating that the basis of SDS resistance may be localized to P1 interactions. The good correlation between SDS sensitivity and the exposure of hydrophobic residues provides a biochemical rationale for the use of this assay to investigate the maturation of class II molecules and the longevity of the complexes.  (+info)

Recombinant domain IV of perlecan binds to nidogens, laminin-nidogen complex, fibronectin, fibulin-2 and heparin. (8/3180)

Domain IV of mouse perlecan, which consists of 14 immunoglobulin superfamily (IG) modules, was prepared from recombinant human cell culture medium in the form of two fragments, IV-1 (IG2-9, 100 kDa) and IV-2 (IG10-15, 66 kDa). Both fragments bound to a heparin column, being eluted at ionic strengths either below (IV-2) or above (IV-1) physiological level, and could thus be readily purified. Electron microscopy demonstrated an elongated shape (20-25 nm), and folding into a native structure was indicated by immunological assay and CD spectroscopy. Solid-phase and surface plasmon resonance assays demonstrated strong binding of fragment IV-1 to fibronectin, nidogen-1, nidogen-2 and the laminin-1-nidogen-1 complex, with Kd values in the range 4-17 nM. The latter binding apparently occurs through nidogen-1, as shown by the formation of ternary complexes. Only moderate binding was observed for fibulin-2 and collagen IV and none for fibulin-1 and BM-40. Fragment IV-2 showed a more restricted pattern of binding, with only weaker binding to fibronectin and fibulin-2. None of these activities could be demonstrated for recombinant fragments corresponding to the N-terminal perlecan domains I to III. This indicates a special role for domain IV in the integration of perlecan into basement membranes and other extracellular structures via protein-protein interactions.  (+info)

Sensors | Free Full-Text | Biosensor Applications in the Field of Antibiotic Research-A Review of Recent DevelopmentsSensors | Free Full-Text | Biosensor Applications in the Field of Antibiotic Research-A Review of Recent Developments
Antibacterials are among of the most important medications used in health care. However, their efficacy is increasingly impeded by a tremendous and globally spread bacterial resistance phenomenon. This bacterial resistance is accelerated by inadequate application of antibacterial drugs in humans, the widespread veterinary use of antibacterials, and antibacterial occurrence in the environment and food. Further, there is a lack of development of innovative novel drugs. Therefore, the search for novel antibacterials has to be intensified and the spread of antibacterials in the environment has to be restricted. Due to the fundamental progress in biosensor development and promising applications in the antibiotic field, this review gives for the first time an overview on the use and prospects of biosensor applications in that area. A number of reports have applied biosensors of different design and techniques to search for antibacterials in environmental and foodstuff matrices. These studies are discussed

Developing New Modalities for Biosensing using Synthetic BiologyDeveloping New Modalities for Biosensing using Synthetic Biology
Biosensors are devices that use biological components to detect important analytes. Biosensing systems have various applications in areas such as medicine, environmental monitoring, and process control. Classical biosensors are often based on bacteria or purified enzymes that have limitations on efficiency or stability. I have developed several new biosensors to overcome these disadvantages. Two preliminary biosensors were first created based on the extremely strong and specific interaction between biotin and (strept)avidin. Both biosensors showed high sensitivity and reliability for measuring biotin with detection limits of 50-1000 pg/ml and 20-100 ng/ml, respectively. Following these, a new biosensor was developed by coupling a mobile, functionalized microsurface with cell-free expression approaches. This biosensor demonstrated a dynamic range of 1- 100 ng/ml. In addition, I also explored the possibility of combining these biosensing systems with engineered living cells. By leveraging the ...

Fluorescent glucose biosensor - WikipediaFluorescent glucose biosensor - Wikipedia
Fluorescent glucose biosensors are devices that measure the concentration of glucose in diabetic patients by means of sensitive protein that relays the concentration by means of fluorescence, an alternative to amperometric sension of glucose. No device has yet entered the medical market, but, due to the prevalence of diabetes, it is the prime drive in the construction of fluorescent biosensors. Keeping glucose levels in check is crucial to minimize the onset of the damage caused by diabetes. As a consequence, in conjunction with insulin administrations, the prime requirement for diabetic patients is to regularly monitor their blood glucose levels. The monitoring systems currently in general use have the drawback of below optimal number of readings, due to their reliance on a drop of fresh blood. Some continuous glucose monitors are commercially available, but suffer from the severe drawback of a short working life of the probe. The majority of these work amperometrically. As a result, there is ...

A novel biosensing approach for the label-free detection of nucleic acid sequences of short and large lengths has been implemented, with special emphasis on targeting RNA sequences with secondary structures. The approach is based on selecting 8-aminoadenine-modified parallel-stranded DNA tail-clamps as affinity bioreceptors. These receptors have the ability of creating a stable triplex-stranded helix at neutral pH upon hybridization with the nucleic acid target. A surface plasmon resonance biosensor has been used for the detection. With this strategy, we have detected short DNA sequences (32-mer) and purified RNA (103-mer) at the femtomol level in a few minutes in an easy and level-free way. This approach is particularly suitable for the detection of RNA molecules with predicted secondary structures, reaching a limit of detection of 50fmol without any label or amplification steps. Our methodology has shown a marked enhancement for the detection (18 for short DNA and 54 for RNA), when compared ...

The plan is for a ten-volume encyclopedia that will collect together and critically evaluate all aspects of the current state of knowledge about the use of nanotechnology in the life sciences. This is certainly one of the most dynamic areas of research at present, and therefore to attempt a comprehensive summary and evaluation is a challenging task. Moreover, this field has the distinction that, perhaps more than any other current area of research, it has inputs from chemistry, biology, biochemistry, materials science, and physics. Therefore, it is important that the knowledge must be communicated in a way that extends beyond the boundaries of the classical ...

A Fluorescent Molecular Sensor for pH Windows in Traditional and Polymeric Biocompatible Micelles: Comicellization of Anionic...A Fluorescent Molecular Sensor for pH Windows in Traditional and Polymeric Biocompatible Micelles: Comicellization of Anionic...
A new approach is presented to obtain fluorescent sensors for pH windows that work in water and under biomimetic conditions. A single molecule that features all-covalently linked components is used, thus making it capable of working as a fluorescent sensor with an OFF/ON/OFF response to pH value. The components are a tertiary amine, a pyridine, and a fluorophore (pyrene). The forms with both protonated bases or both neutral bases quench the pyrene fluorescence, whereas the form with the neutral pyridine and protonated amine groups is fluorescent. The molecular sensor is also equipped with a long alkyl chain to make it highly hydrophobic in all its protonated and unprotonated forms, that is, either when neutral or charged. Accordingly, it can be confined at any pH value either in traditional (i.e., low-molecular-weight) nonionic surfactant micelles or inside polymeric, biocompatible micellar containers. Relevant for future applications in vivo, thanks to its strong hydrophobicity, no leakage of ...

N2 - Alizarin-phenylboronic acid interactions were used in a new design strategy for self-organized fluorescent sensors of metal ions and anions. First, Alizarin Red S (ARS), which binds effectively to phenylboronic acid (PBA) at neutral conditions in water, proved to be an excellent fluorescent indicator for the selective detection of metal ions; the fluorescent-active ARS-PBA ensemble causes an efficient and selective quenching in the fluorescence by adding metal ions. It was also found that anion-induced phenylboronates can bind effectively to alizarin and greatly enhance the fluorescence in MeOH. The observation makes it possible to design new self-organized anion sensory systems composed of alizarin (as reporter) and phenylboronic acids ...

Design and construction of a portable whole-cell living bacterial biosensor for the detection of arsenic in water - InfoscienceDesign and construction of a portable whole-cell living bacterial biosensor for the detection of arsenic in water - Infoscience
Contamination of drinking water with arsenic is a recurring problem in both industrialized and developing countries. Supplies for large populations can have concentrations much higher than the permissible levels, set by the World Health Organization (WHO) to 10 μg As/L for most European countries and the United States and to 50 μg As/L elsewhere. As arsenic analysis requires high-end instruments, which are largely unavailable in developing countries, bioassays based on genetically engineered bacteria have been proposed as suitable alternatives. Yet, such tests would profit from better standardization and direct incorporation into sensing devices. The final objective of this work was to develop a microfluidic device in which bacterial bioreporters could be embedded, actively maintained for at least one week, exposed to arsenic and which allowed direct detection of the reporter signal produced, as a further step towards a complete miniaturized bacterial biosensor. The signal element in the biosensor is

Molecular sensor - WikipediaMolecular sensor - Wikipedia
A molecular sensor or chemosensor is a molecule that interacts with an analyte to produce a detectable change. Molecular sensors combine molecular recognition with some form of reporter so the presence of the guest can be observed. The term supramolecular analytical chemistry has recently been coined to describe the application of molecular sensors to analytical chemistry. Early examples of molecular sensors are crown ethers with large affinity for sodium ions but not for potassium and forms of metal detection by so-called complexones which are traditional pH indicators retrofitted with molecular groups sensitive to metals. This receptor-spacer-reporter concept is a recurring theme often with the reporter displaying photoinduced electron transfer (PET). One example is a sensor sensitive to heparin. Other receptors are sensitive not to a specific molecule but to a molecular compound class. One example is the grouped analysis of several tannic acids that accumulate in ageing Scotch whisky in oak ...

The simultaneous detection of multiple analytes is an important consideration for the advancement of biosensor technology. Currently, few sensor systems possess the capability to accurately and precisely detect multiple antigens. This work presents a simple approach for the functionalization of sensor surfaces suitable for multichannel detection. This approach utilizes self-assembled monolayer (SAM) chemistry to create a nonfouling, functional sensor platform based on biotinylated single-stranded DNA immobilized via a streptavidin bridge to a mixed SAM of biotinylated alkanethiol and oligo(ethylene glycol). Nonspecific binding is minimized with the nonfouling background of the sensor surface. A usable protein chip is generated by applying protein-DNA conjugates which are directed to specific sites on the sensor chip surface by utilizing the specificity of DNA hybridization. The described platform is demonstrated in a custom-built surface plasmon resonance biosensor. The detection capabilities of ...

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 ...

Handheld electrochemical sensors are part of the daily routine for millions of people with diabetes around the globe who monitor their blood sugar levels with electric glucometers. While such sensors have revolutionized at-home medical testing for diabetics, they have not yet been successfully applied to diagnosing other conditions. Sensors like glucometers detect glucose in blood based on the activity of an enzyme, and there are only a limited number of enzymes that can be used to sense biomarkers of human disease. An alternative detection strategy based on binding events between antibodies and their molecular targets have been investigated to expand the use of electrochemical sensors for medicine, but these sensors fall victim to the rapid accumulation of fouling substances from biological fluids on their conductive surfaces, which deactivate them. Existing antifouling coatings are difficult to mass-manufacture, suffer from quality and consistency issues, and are not very effective.. ...

Hierarchical CuO/ZnO membranes for environmental applications under the irradiation of visible light | DR-NTUHierarchical CuO/ZnO membranes for environmental applications under the irradiation of visible light | DR-NTU
Solar visible light is a source of clean and cheap energy. Herein, a new kind of hierarchical CuO/ZnO nanomaterial was synthesized using a facile process. Characterized by FESEM, TEM, XRD, XPS, and so forth, this CuO/ZnO naomaterial shows a special hierarchical nanostructure with CuO nanoparticles grown on ZnO nanorods. By assembling the hierarchical CuO/ZnO nanomaterials on a piece of commercial glassfiber membrane, a novel hierarchical CuO/ZnO membrane was fabricated. This CuO/ZnO membrane demonstrated excellent environmental applications, such as improved photodegradation of contaminants and antibacterial activity, under the irradiation of visible light. Compared with pure ZnO nanorod membrane, the improved photodegradation and antibacterial capacities of this hierarchical CuO/ZnO membrane result from the special hierarchical nanostructure of CuO/ZnO nanomaterials, which could enhance light utilization rate, enlarge specific surface area, and retard the recombination of electrons and holes at ...

Novel Applications of Graphene in Medical and Biosensor ApplicationsNovel Applications of Graphene in Medical and Biosensor Applications
Reduced Graphene Oxide (rGO) is a good absorber of light, and is a potential material for use in photothermal therapy. rGO-based nanocomposites have been considered for cancer theranostics, but this method has rarely been used for pathogen destruction. This is even more surprising considering the widespread commercial availability of graphene oxide.. Graphenea explored the possibility of destroying E. coli pathogens in its study featured in the Journal of Materials Chemistry B. Reduced graphene oxide (rGO-PEG- NH2) and Au nanorods (Nrs) coated with rGO-PEG-NH2 were used to destroy the pathogens by laser irradiation. The rGO-PEG coating serves a dual purpose by mitigating the toxicity of Au NRs and improving the overall photo-thermal process and so the temperatures reachable.. In this paper, Graphenea showed 99% bacterial killing efficiency at low concentrations (20-49mg/ml) in a water solution, demonstrating the potential of reduced graphene oxide as an effective anti-pathogen agent.. In another ...

Aptamers, which are in vitro-selected functional oligonucleotides, have been employed to design novel aptasensor due to their inherent high selectivity and affinity compared to traditional biorecognition elements. This report presents a novel aptamer biosensor for determining the endocrine disrupting compound (EDC), 17~-estradiol (E2), which was constructed from a SELEX-synthesized 76-mer biotinylated aptamer for 17~-estradiol incorporated in a dendritic generation 1 poly(propylene imine)- poly thiophene (G 1PPT-co-PEDOT) star copolymer-functionalised Au electrode via biotin-avidin interaction. The sensor platform and aptasensor were interrogated with scanning electron microscopy (SEM), FTIR, electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV) and square wave voltammetry (SWV). The kinetic parameters of the sensor platform were determined by modelling the [Fe(CN)6r3/ - 4 (redox probe) Nyquist and Bode impedimetric spectra to the appropriate equivalent electrical circuit.

Advancements in electrochemical DNA sensor for detection of human papilloma virus - A reviewAdvancements in electrochemical DNA sensor for detection of human papilloma virus - A review
Human papillomavirus (HPV) is one of the most common sexually transmitted disease, transmitted through intimate skin contact or mucosal membrane. The HPV virus consists of a double-stranded circular DNA and the role of HPV virus in cervical cancer has been studied extensively. Thus it is critical to develop rapid identification method for early detection of the virus. A portable biosensing device could give rapid and reliable results for the identification and quantitative determination of the virus. The fabrication of electrochemical biosensors is one of the current techniques utilized to achieve this aim. In such electrochemical biosensors, a single-strand DNA is immobilized onto an electrically conducting surface and the changes in electrical parameters due to the hybridization on the electrode surface are measured. This review covers the recent developments in electrochemical DNA biosensors for the detection of HPV virus. Due to the several advantages of electrochemical DNA biosensors, their ...

Ultrasensitive Impedimetric Biosensor Fabricated by a New Immobilisation Technique for Parathyroid Hormone | AVESİSUltrasensitive Impedimetric Biosensor Fabricated by a New Immobilisation Technique for Parathyroid Hormone | AVESİS
This paper presents a novel ultrasensitive and rapid impedimetric biosensor with new immobilisation materials for parathyroid hormone (PTH) with the aim to determine the PTH level in serum for the diagnosis and monitoring of parathyroid diseases such as hyperparathyroidism, adenoma, and thyroid cancer. The interaction between PTH and the biosensor was investigated with an electrochemical method. The biosensor was based on the gold electrode modified by mercaptohexanol (6-MHL). Anti-parathyroid hormone (anti-PTH) was covalently immobilised onto a self-assembled monolayer (SAM) by using epiclorhidrina (EPI) with ethanolamine (EA). The EPI-EA interaction represents the first use of these for the construction of biosensors in published reports. The immobilisation of the anti-PTH was monitored by electrochemical impedance spectroscopy, cyclic voltammetry and scanning electron microscopy (SEM) techniques. After the optimisation studies of immobilisation materials such as 6-MHL, EPI, EA and ...

IDEALS @ Illinois: Evaluation of immobilizing horseradish peroxidase and alcohol oxidase in PVA-AWP polymerIDEALS @ Illinois: Evaluation of immobilizing horseradish peroxidase and alcohol oxidase in PVA-AWP polymer
Biosensor technology is a powerful alternative to conventional analytical techniques, harnessing the specificity and sensitivity of biological systems in small, low cost devices. One of the factors that affect the performance of a biosensor is the immobilization of the biological sensing element, or bioreceptor, on the transducer surface. The objectives of this study were to determine the effects of polymer concentration, ultraviolet (UV) light exposure, and film thickness on the activity and stability of horseradish peroxidase (HRP) and alcohol oxidase (AOX) when immobilized in a photo-crosslinkable and water-soluble polymer, poly (vinyl alcohol) azide-unit water pendant (PVA-AWP). The immobilized enzyme films were to be used in biosensing applications and their stability and activity were determined colorimetrically and electrochemically. Compared to other gel immobilization techniques, PVA hydrogels offer several advantages, such as better elasticity, low-toxicity, biocompatibility with ...

Surface plasmon resonance (SPR) biosensors are used to characterize and quantify biomolecular interactions. Real-time and fast measurement, high sensitivity and specificity, no need of labeled reagents are the unique properties of SPR biosensors. SPR biosensors have been used for detection of several analytes. Recently, molecular imprinting technology is used for creation of biorecognition surfaces on the SPR biosensors. Molecular imprinting is the technology of designing materials with robust recognition sites suitable for interaction with the print molecule. Due to their stability in complex matrices under tough conditions, ease of preparation, low cost, reusability, high recognition capacity to the template molecule and binding characteristics as high as those of natural binders, molecularly imprinted polymers (MIPs) are extensively used in a variety of areas, such as catalysis, separations, solid-phase extractions and biosensors.

BACKGROUND: Direct acting antivirals (DAAs) provide efficient hepatitis C virus (HCV) therapy and clearance for a majority of patients, but are not available or effective for all patients. They risk developing HCV-induced hepatocellular carcinoma (HCC), for which the mechanism remains obscure and therapy is missing. Annexin A2 (AnxA2) has been reported to co-precipitate with the non-structural (NS) HCV proteins NS5B and NS3/NS4A, indicating a role in HCC tumorigenesis and effect on DAA therapy.. METHODS: Surface plasmon resonance biosensor technology was used to characterize direct interactions between AnxA2 and HCV NS5B, NS3/NS4 and RNA, and the subsequent effects on catalysis and inhibition.. RESULTS: No direct interaction between AnxA2 and NS3/NS4A was detected, while AnxA2 formed a slowly dissociating, high affinity (K D = 30 nM), complex with NS5B, decreasing its catalytic activity and affinity for the allosteric inhibitor filibuvir. The RNA binding of the two proteins was independent and ...

Cardiac myocytes have provided a key paradigm for the concept of the compartmentalized cAMP generation sensed by AKAP-anchored PKA. Phosphodiesterases (PDEs) provide the sole route for degrading cAMP in cells and are thus poised to regulate intracellular cAMP gradients. PDE3 and PDE4 represent the major cAMP degrading activities in rat ventriculocytes. By performing real-time imaging of cAMP in situ, we establish the hierarchy of these PDEs in controlling cAMP levels in basal conditions and on stimulation with a beta-adrenergic receptor agonist. PDE4, rather than PDE3, appears to be responsible for modulating the amplitude and duration of the cAMP response to beta-agonists. PDE3 and PDE4 localize to distinct compartments and this may underpin their different functional roles. Our findings indicate the importance of distinctly localized PDE isoenzymes in determining compartmentalized cAMP signaling.

Graphene-based electrochemical sensor can detect COVID-19 in less than five minutes | Graphene-InfoGraphene-based electrochemical sensor can detect COVID-19 in less than five minutes | Graphene-Info
There are two broad categories of COVID-19 tests on the market. The first category uses reverse transcriptase real-time polymerase chain reaction (RT-PCR) and nucleic acid hybridization strategies to identify viral RNA. Current FDA-approved diagnostic tests use this technique. Some drawbacks include the amount of time it takes to complete the test, the need for specialized personnel and the availability of equipment and reagents. The second category of tests focuses on the detection of antibodies. However, there could be a delay of a few days to a few weeks after a person has been exposed to the virus for them to produce detectable antibodies.. In recent years, researchers have had some success with creating point-of-care biosensors using 2D nanomaterials such as graphene to detect diseases. The main advantages of graphene-based biosensors are their sensitivity, low cost of production and rapid detection turnaround. The discovery of graphene opened up a new era of sensor development due to its ...

Simultaneous live cell imaging using dual FRET sensors with a single excitation light<...Simultaneous live cell imaging using dual FRET sensors with a single excitation light<...
TY - JOUR. T1 - Simultaneous live cell imaging using dual FRET sensors with a single excitation light. AU - Niino, Yusuke. AU - Hotta, Kohji. AU - Oka, Kotaro. PY - 2009/6/24. Y1 - 2009/6/24. N2 - Fluorescence resonance energy transfer (FRET) between fluorescent proteins is a powerful tool for visualization of signal transduction in living cells, and recently, some strategies for imaging of dual FRET pairs in a single cell have been reported. However, these necessitate alteration of excitation light between two different wavelengths to avoid the spectral overlap, resulting in sequential detection with a lag time. Thus, to follow fast signal dynamics or signal changes in highly motile cells, a single-excitation dual-FRET method should be required. Here we reported this by using four-color imaging with a single excitation light and subsequent linear unmixing to distinguish fluorescent proteins. We constructed new FRET sensors with Sapphire/RFP to combine with CFP/YFP, and accomplished simultaneous ...
