An Enzyme Electrode for Glucose Consisting of Glucose Oxidase Immobilised at a Benzoquinone-Modified Carbon Electrode

This paper describes an amperometric enzyme electrode for the analysis of glucose. The glucose sensor utilised adsorbed benzoquinone on a carbon electrode to mediate electron transfer from glucose oxidase. A linear response to 0–15 mM glucose was observed. The electrode's response to glucose, its pH profile and the effect of temperature are presented.
