Abstract CuO nanospheres, synthesized by a simple one‐step hydrothermal method, have been applied to modify the glassy carbon (GC) electrode for sensitive nonenzymatic glucose detection. The nanospheres modified electrode, compared Nafion GC exhibits an enhanced electrocatalytic property direct oxidation and shows fast response high sensitivity amperometric detection of glucose. It has determined that dissolved oxygen is not involved in concentration NaCl does poison electrode. These results...
As broad-spectrum pesticides, organophosphates (OPs) are widely used in agriculture all over the world. However, due to their neurotoxicity humans and increasing occurrence environment, there is growing interest sensitive selective detection. This paper reports a new cost-effective plant esterase–chitosan/gold nanoparticles–graphene nanosheet (PLaE-CS/AuNPs-GNs) biosensor for detection of methyl parathion malathion. Highly pure esterase produced from plants at low cost shares same inhibition...
The TiO2-Pt hybrid nanofibers with an average dia. 72.6 nm were fabricated by electrospinning poly(vinylpyrrolidone)-ethanol solution containing platinum acetate and titanium tetraisopropoxide, followed calcination in air at 500 °C for 3 h. High resolution TEM showed that Pt nanoparticles diameter of ∼2 well dispersed the anatase TiO2 nanofibers. Compared to pristine (average 67.7 nm), incorporation into can greatly enhance oxidation hydrazine neutral solution. amperometric sensor, using...
Platinum nanomaterials have shown to be highly attractive due their superior catalytic ability with high utilization efficiency. Electrodeposition is a flexible technique produce nanostructures controllable morphology and purity. In this study, platinum nanoparticles tunable structure were synthesized on single-walled carbon nanotube membrane via cyclic voltammetry. Specifically, Pt nanoflower monolayer consisting of numerous petal-like nanosheets specific surface area was obtained under the...
As the most common type of harsh environment sensors, high temperature gas sensors are paramount importance to improve combustion efficiency and control emissions. In this study, large scale polycrystalline CeO2 nanofibers were prepared with an average diameter 376 ± 55 nm using a facile two-step synthesis route including electrospinning calcination. The as-prepared show good morphological structural stability in (800–1000 °C). further employed for situ, real-time oxygen (O2) carbon monoxide...
To overcome shortcomings of the ex situ approaches, in detection using H2O2 molecules to diagnose ischemia through enhanced protein direct electron transfer on a unique horseradish peroxidase–Au nanoparticles–polyaniline nanowires biofilm is demonstrated and it discovered that extracellular molecule released per ischemic cell 2.7-times normal cell.

These results...
Abstract A novel single‐walled carbon nanotube (SWNT) based biosensor for real‐time detection of organophosphate has been developed. Horizontally aligned SWNTs are assembled to desirable electrodes using AC dielectrophoresis technique. Organophosphorus hydrolase (OPH) immobilized on the by nonspecific binding triggers enzymatic hydrolysis organophosphates (OPs), such as paraoxon, consequently causing a detectable change in conductance SWNTs. The is found be correlated concentration...
Abstract A novel L‐cysteine (CysH) electrochemical sensor based on CeO 2 nanofibers (NFs) modified screen printed carbon electrodes (SPCEs) was developed. The morphology and the structure of as‐prepared NFs were first characterized using scanning electron microscopy (SEM) X‐ray diffraction pattern (XRD), respectively. electrocatalytic performances SPCEs then evaluated cyclic voltammetry amperometry. Experimental results showed that possess excellent activity toward detection CysH....
By calcining electrospun La(NO3)3–Sr(NO3)2–Mn(NO3)2–PVP precursory nanofibers, La0.67Sr0.33MnO3 (LSMO) nanofibers have been successfully fabricated on a large scale.
