Hybrid metalloprotein-nanoparticle

Figure 8-7. A Schematic view of a redox molecule or metalloprotein in the gap between a substrate and a tip electrode in STM or between two nanogap electrodes. B Electronic energy scheme for in situ STM of the redox molecule. C Tunnel junction with a redox molecule and a metallic nanoparticle in a hybrid structure. D Energy scheme corresponding to the hybrid structure with two potential drops.

The chapters in this volume offer overviews of electronic properties, electron transfer and electron-proton coupled charge transfer of biological molecules and macromolecules both in the natural aqueous solution environment and on metallic electrode surfaces, where the electrochemical potential controls biomolecular function. Redox metalloproteins and DNA-based molecules are primary targets, but amino acid and nucleobase building blocks are also addressed. Novel enviromnents where proteins and DNA-based molecules are inserted in metallic nanoparticle hybrids or in situ STM configurations are other focus areas.
