Analysis of glucose oxidase activity Oxidation of o-dianisidine forms a quinoneimine dye that is measured spectrophotometrically at 500 nm. The benzoquinone can be used for spectrophotometric measurement of glucose oxidase activity. Reaction mixtures containing 1 M glucose, 0.1% benzoquinone, and 0.1 ...
The acid used controls the relative concentrations of each silicon precursor present in the reaction mixture and through that controls also the concentration of iron effectively incorporated into the framework. For HF and HCl reaction mixtures, Fe(III) is already in tetrahedral geometry in the solid...
The reaction of glucose catalyzed by GOD can release electrons and result in the significant open-circuit voltage (EOCV) of the biosensor due to the reduction reaction occurred on the cathode. . When l-Cys is present, l-Cys forms an insoluble thiolate with Ag+. As a result, the ...
Construction of carboxyl functional groups and their enhancement effect for methanol electrocatalytic oxidation reaction In this paper, we investigated the effect of ozone oxidation on properties of commercial carbon black supported platinum (Pt) nanoparticles for the methano...

1c). Hence, we envisioned a formal asymmetric α-benzylation of cyclic carbonyls. Yin et al. established an organobismuth complex/aliphatic amine system for the synthesis of exocyclic α,β-unsaturated compounds via aldol condensation under mild reaction conditions31, providing a potential chemo...
Annperometric biosensors are based on redox reactions, namely the oxidation/reduction of electroactive species generated/consumed in an enzyme-reaction. Optical biosensors rely on the measurement of an optical property that varies as a result of the enzymic reaction. Thermal biosensors rely on the ...
