Amperometric determination of bonded glucose with an MnO2 and glucose oxidase bulk-modified screen-printed electrode using flow-injection analysis

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…”

Manganese Dioxide Nanostructures as a Novel Electrochemical Mediator for Thiol Sensors

“…Therefore, MnO 2 of various origins has been extensively used as an oxidationÀreduction mediator in the development of peroxide-sensitive electrochemical sensors and biosensors based on oxidoreductases [10,[12][13][14]. However, the studies do not provide a systemic investigation of analytical characteristics of the developed (bio)sensors as a function of the MnO 2 dimensions and type of crystal structure.…”

Gold nanoparticles mediate the assembly of manganese dioxide nanoparticles for H2O2 amperometric sensing

“…Manganese dioxide nanoparticles (nano-MnO 2 ) have drawn attention for electrochemical H 2 O 2 sensing because they have been proven to be excellent catalytic substances that promote H 2 O 2 decomposition and have been widely applied in bioanalytical chemistry [18][19][20][21]. Yao and Hu reported a glassy carbon electrode (GCE) modified with nano-MnO 2 and a Na-montmorillonite composite that had a sensitivity of 3.14 × 10 4 A M −1 cm −2 [20].…”
