Electron Transfer in Active Enzyme Molecules Adsorbed on Electrodes: Studies and Exploits of the Coupling to Proton Transfer and Catalysis.

摘要

Enzyme molecules can be bound at electrodes such that interfacial electron transfer (ET) is sufficiently fast to study and exploit all the exquisite chemistry that these complex catalysts normally perform.There are many ongoing efforts to develop suitable electrodes,which include materials ranging from graphite to metals modified with surfactants and self-assembled monolayers of organo-thiols [1].The nature and details of the interactions between protein and electrode are far from clear [2].
