title: Electrochemically induced surface-enhanced infrared difference absorption (SEIDA) spectroscopy of a protein monolayer.
abstract: Functional infrared difference spectra of a protein monolayer are recorded by exploiting the surface enhancement exerted by a modified gold surface. The noble metal is used as the working electrode to induce redox-linked structural changes in the single layer of cytochrome c. The observed differences in the relative band intensities as compared to the difference spectrum of cytochrome c in solution are attributed to orientational effects of the adsorbed protein.
