Abstract

New membrane-protein based electrodes were prepared incorporating cytochrome bo₃ from Escherichia coli and gold nanoparticles. Direct electron transfer between the electrode and the immobilized enzymes was achieved, resulting in an electrocatalytic activity in presence of O ₂. The size of the gold nanoparticles was shown to be important and smaller particles were shown to reduce the overpotential of the process.
