摘要:
An amperometric enzyme electrode for the determination of glucose (<16mmol−1) is constructed by incorporating electron mediators tetrathiafulvalene in Nafion and subsequently coating with immobilized glucose oxidase. The results obtained from measurements of glucose in fermentation samples containing biomass or molasses indicate the utility of the electrode for glucose assay in such media over at least 12 weeks. Digital simulation is employed to study the cyclic voltammetry (CV) of Tetrathiafulvalene-Glucose Oxidase-Modified Glassy Carbon Electrode (TTF-GOD-GCE); the digital model is built and the effects of kinetic parameters on CV-curves are discussed. The response process of the Tetrathiafulvalene-Glucose Oxidase-Modified Electrode is partly explained by the simulation results and further research is expected to guide the design of biosensors and improve the properties of the enzyme-mediator modified electrode.
