Abstract
The enzyme glucose oxidase (GOx) reduces, in the presence of glucose and under anaerobic conditions, PtCl62- to Pt nanoclusters (NCs) that are implanted in the protein. The assembly of the Pt NC/GOx hybrid on a dithiol monolayer yields an electrically contacted enzyme electrode, and the bioelectrocatalytic oxidation of glucose is activated (turnover rate ca. 2780 ± 70 s-1). The Pt NC/GOx hybrid is also used, under anaerobic conditions, as a biocatalyst for H2 evolution.
