Interfacing Natural and Artificial Proteins with Electronic Devices

摘要: Integration of modern nanoelectronic technology with the potent molecular machines living organisms provides opportunities to engineer controlled energy transfer in catalysts, solar cells, chemical sensors, and opto-electronics. To enable production bioelectronic devices that combine functionalities biomolecules inorganic components, we are investigating properties assembly proteins at conductive interfaces. Since many key cellular functions accomplished through system enzymes redox carrier molecules very complicated unstable, have adopted a different approach: reproducing functional protein features within smaller, simpler, more robust model proteins, maquettes. test functionality, developed facile method covalently attach polyhistidine-tagged natural maquettes graphene field effect transistors (FETs), nanotubes highly ordered pyrolytic graphite. Atomic Force Microscopy Raman spectroscopy used gain structural understanding protein-carbon interface, while current-gate voltage measurements elucidate electronic properties. We will demonstrate how these detect changes light-activated including green yellow fluorescent Zn-protoporphyrin IX flavin containing
