Surface-Enhanced Resonance Raman Spectroscopic and Electrochemical Study of Cytochrome c Bound on Electrodes through Coordination with Pyridinyl-Terminated Self-Assembled Monolayers


Cytochrome c (Cyt-c) is immobilized on Ag and Au electrodes coated with self-assembled monolayers (SAM), comprised of pyridine-terminated alkanethiols and a shorter chain diluent thiol. Surface-enhanced resonance Raman (SERR) spectroscopy of coated Ag electrodes reveals that the adsorbed Cyt-c forms a potentialdependent coordination equilibrium with a… (More)
