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. © 2012 Elsevier B.V. All rights reserved.
