Notes:
This article describes the application of ferrocene-modified n-type silicon electrodes to the anaerobic redox catalysis of glucose oxidase. The electrodes are modified with ferrocene either directly, by using (1,1′-ferrocenediyl)dichlorosilane, or via an underlying polypyrrole film. Light-activated catalytic waves are detected in both cases in the presence of glucose oxidase and glucose, thereby demonstrating rapid heterogeneous kinetics between the covalently immobilized mediator and glucose oxidase. A glucose-sensitive electrode is made by simple adsorption of glucose oxidase from an aqueous buffered solution into the surface film.
