“…Zhou et al [22]investigated a sensitive and selective amperometric glucose biosensor based on platinum microparticles dispersed in nanofibrous PAN. PAN hybrid materials, which combine PAN with other kinds of nanomaterials, especially metal nanoparticles [23], play an important role in biosensors and electrochemical sensors [24,25]. During recent years, bimetallic alloy nanoparticles, such as Au-Pt, Pt-Fe, Pt-Ni, Pt-Co, and Pt-Cr [26 -28] etc., have attracted considerable interest in the field of catalysis and sensors because they often exhibit better catalytic properties than do their monometallic counterparts.…”

Based on the immobilization of horseradish peroxidase (HRP) in chitosan(CS) on a glassy carbon electrode (GCE) modified with the Au-Pt alloy nanoparticles (NPs) / polyaniline nanotube (nanoPAN) nanocomposite film, a novel hydrogen peroxide biosensor was constructed. The modified processes of GCE were monitored by cyclic voltammetry and electrochemical impedance spectroscopy. Au-PtNPs/nanoPAN/CS had a better synergistic electrochemical effect than did AuNPs/nanoPAN/CS or PtNPs/nanoPAN/CS. The amperometric response of the biosensor towards H 2 O 2 was investigated by successively adding aliquots of H 2 O 2 to a continuous stirring phosphate buffer solution under the optimized conditions. Because Au-PtNPs have unique catalytic properties and good biocompatibility, and especially Au-PtNPs and nanoPAN have synergistic augmentation for facilitating electron-transfer, the biosensor displayed a fast response time (< 2 s) and broad linear response to H 2 O 2 in the range from 1.0 to 2200 mmol L À1 with a relatively low detection limit of 0.5 mmol L À1 at 3 times the background noise. Moreover, the biosensor can be applied in practical analysis and exhibited high sensitivity, good reproducibility, and long-term stability.

“…30 Over 0.6 V, the response was controlled normally by diffusion of the substrate and the product. 37 In this case, the influence of H + yielded after rapid electro-oxidation is dominant. The yielded H + not diffused into bulk solution may accumulate in the biomembrane due to an excess negatively charge of the hybrid system, resulting in a shift of the local pH within the hybrid biocoating and hence to a decrease in the enzymatic rate.…”

“…Polymer films, and particularly those based on substituted aromatic compounds, such as aniline, present interesting characteristics, namely high conductivity, stability, durability, and reproducibility associated with low costs (Bhadra et al, 2009;Casella & Guascito, 1997;Gornall et al, 2009;Grennan et al, 2006;Huang et al, 2002Huang et al, , 2003Šeděnková et al, 2008;Shan et al, 2008;Trashin et al, 2009;Waltman & Bargon, 1986;Yin et al, 2006). Their main drawback is related to their preparation which involves handling of the respective monomers which are potentially hazardous materials.…”

Disposable screen-printed electrodes (SPCE) were modified using a cosmetic product to partially block the electrode surface in order to obtain a microelectrode array. The microarrays formed were electropolymerized with aniline. Scanning electron microscopy was used to evaluate the modified and polymerized electrode surface. Electrochemical characteristics of the constructed sensor for cadmium analysis were evaluated by cyclic and square-wave voltammetry. Optimized stripping procedure in which the preconcentration of cadmium was achieved by depositing at -1.20 V (vs. Ag/AgCl) resulted in a well defined anodic peak at approximately -0.7 V at pH 4.6. The achieved limit of detection was 4 × 10 −9 mol dm −3. Spray modified and polymerized microarray electrodes were successfully applied to quantify cadmium in fish sample digests.
