Amperometric Hydrogen Peroxide Sensors with Multivalent Metal Oxide-Modified Electrodes for Biomedical Analysis

Screen-Printed Electrodes Modified with Metal Nanoparticles for Small Molecule Sensing

“…Platinum group metallic NPs are a well-known electrocatalyst towards the oxidation or reduction of hydrogen peroxide [70]. The mechanism involved [71] is shown in Figure 2a.…”

Determination of H2O2 by MnO2 modified screen printed carbon electrode during Fenton and visible light-assisted photo-Fenton based removal of acetamiprid from water

“…Basically, the process includes the activation of H 2 O 2 by appropriate salts of Fe 2+ , which launches the generation of OH • (radicals with high redox potential, 2.8 V vs. the normal hydrogen electrode [17,18,21,22]) with the ability to attack different organic compounds (RH) leading to chain oxidation of the targets to stable intermediate(s), or more preferably even to the complete mineralization [11][12][13][14][15][16][17][18][19][20][21][22][23]. The process(es) can be assumed with complex radical mechanisms [23]: [24][25][26][27][28][29][30][31][32]42], which are sensitive to acids and basis, over the oxides of…”

A new amperometric glucose biosensor based on screen printed carbon electrodes with rhenium(IV) - oxide as a mediator

“…It was immobilized on the surface of the ReO 2 -modified SPCEs using a Nafion membrane [23]. The sensor responds well to injections of glucose under FIA conditions.…”
