Abstract

An enzymatic biofuel cell is integrated on a screen-printed electrode as a basis for a self-powered biosensor. A glucose/O₂ biofuel cell consisting of a pyrroloquinoline quinone-dependent glucose dehydrogenase embedded within an Os-complex modified redox polymer bioanode to oxidize glucose and a non-limiting bilirubin oxidase-based gas diffusion biocathode in the direct-electron transfer regime for the reduction of O₂ showed a glucose-dependent current and power output. For full integration on a single screen-printed electrode, a miniaturized agar salt bridge was introduced between the two bioelectrodes to ensure operation of the assembly in a two-compartment configuration with each electrode operating at optimal conditions.
