Direct electron transfer between heme-containing enzymes and electrodes asbasis for third generation biosensors

Direct electron transfer (DET) between redox enzymes and electrodes found t he basis for third generation biosensors. Recent investigations in the auth ors' laboratories on the bioelectrochemistry of heme-containing proteins an d enzymes, primarily peroxidases, but also cellobiose dehydrogenase, will b e reviewed.
