[ 1 ] - Electrochemical Sensing of H2S Gas in Air by Carboxylated Multi-walled Carbon Nanotubes
The electrochemical sensor for detecting hydrogen sulfide was fabricated. H2S gas molecules pass through polytetrafluoroethylene membrane with 0.22 mm pore size. Carboxylated multi-walled carbon nanotubes (MWCNTs-COOH) were used to fabricate working and counter electrodes. It can be seen from Field Emission Scanning Electron Microscopy (FESEM) images of the working electrode that...
[ 2 ] - A Novel Choline Biosensor Based on Immobilization of Enzyme Choline Oxidase on the β-Ga2O3 Nanowires Modified Working Electrode
This article is a report on a novel and high-stability biosensor with minor interference effects of surface modification of working electrode with β-Ga2O3 nanowires (NWs) on choline oxidase biosensor were investigated in an electrochemical detection system. β-Ga2O3 NWs were materialized on the silicon substrate in a catalyst-free growth mechanism. The β-Ga2O<sub...
