In this work, silver nanoparticles decorated onto polyaniline nanowires were synthesized site-specifically Pt working electrodes (with only 0.8 mm2 area) using a novel, rapid, and effective electrochemical procedure: electropolymerization of PANi NWs electrodeposition AgNPs. The complementary properties AgNPs obtained, including high surface area, activity, biocompatibility, chemical stability good adhesion with the electrode surface. Obtained results showed advantages electrosynthesis...
Polyaniline (PANI) conducting polymers have attracted increasing interest as a transducer material for biosensors applications. In this study, we demonstrate the use of PANI nanowires (NWs) immobilization platforms in configuration an electrochemical immunosensor label free detection Japanese encephalitis virus. The NWs were synthesized on surface interdigitated platinum (Pt) microelectrode via growth. morphology and characteristics Pt verified by scanning electron microscopy Fourier...
Surface modification of interdigitated DNA sensors by polypyrrole nanowires and gold nanoparticles has been analyzed systematically. Polypyrrole with diameter 200 nm length 5 μm were electrochemically synthesized on the surface electrodes subsequently decorated 20 nanoparticles. Electrochemical impedance spectroscopy differential voltage measurements conducted to detect concentrations. We have observed a logarithmic dependence analytical signals concentration. A formula for estimating limit...
In this study, a simple, label-free, electrochemical immunosensor system, including three-electrode transducer and microchamber, was designed, fabricated, integrated with focus toward the detection of Newcastle disease virus (NDV). The chicken egg yolk antibodies (IgY) against NDV were used as biological recognition element, replacing purified IgG that require complex extraction process time-consuming. IgY immobilized on sensor surface using PrA/GA SAM/NHS approaches. showed high sensitivity...
ZnO precipitation experiments were carried out in a Trizma (tris(hydroxymethyl)aminomethane)-buffered aqueous solution at 37 °C and the presence of three ZnO-binding 12-mer peptide pairs, which have nearly same isoelectric point (pI). With this new approach, influence sequences on mineralization under moderate conditions was investigated. Previous work focused electrostatic interactions between inorganic-binding peptides inorganic surfaces. The precipitates characterized by X-ray...
Polypyrrole nanowires were electrochemically synthesised on platinum electrode at ambient temperature. The potentiostatic potential was set 0.75 V in the presence of gelatin as soft mould. whole process only took few hundred seconds. morphologies, chemical composition and conductivity evaluated by means Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FT–IR) cyclic voltammetry (CV). obtained nano–wire is around 50 nm diameter with large surface, good conductivity....
Label-free electrochemical DNA sensor is a promising technique for simple, fast, on-site virus detection. However, the low sensitivity still challenge this method. This report shows way to improve by magnetic enrichment of concentration before measuring sensor. The was performed conjugating superparamagnetic nanoparticles with probe single strand. Then, system nanoparticles-DNA matched target followed decantation and compulsorily unfolding strands at high temperature. obtained solution...
