Recent advances in nanobiotechnology involve the use of biomolecule-nanoparticle (NP) hybrid systems for bioelectronic applications. This is exemplified by the electrical contacting of redox enzymes by means of Au-NPs. The enzymes, glucose oxidase, G

Redox enzymes in bioelectronic devices usually lack direct electrical contact with electrodes, owing to the spatial separation of their redox centers from the conductive surfaces by the protein shells. The reconstitution of apo-enzymes on cofactor-fu
