Abstract:

Membrane structures containing the visual receptor protein, rhodopsin, were formed by detergent dialysis on platinum, silicon oxide, titanium oxide and indiumtin oxide electrodes. Electrochemical impedance spectroscopy was used to evaluate the biomembrane structures and their electrical properties. A model equivalent circuit is proposed to describe the membrane electrode interface. The data suggest that the surface structure is a relatively complete single membrane bilayer with a coverage of 0.97, and with longterm stability.
