Impedance Analysis of Surface-Bound Biomembranes
Abstract
Electrochemical impedance analysis was used to characterize biomembrane structures formed on Silicon/Silicon Dioxide, Titanium Dioxide, Indium/Tin Oxide and Platinum electrode surfaces by detergent dialysis. A model equivalent circuit is proposed to describe the membrane/electrode interface. The data suggest that the surface structure is a single membrane layer with resistance of 800 ohms per centimeters squared and capacitance of 550 nf/cm2. Keywords: AC impedance, Biomembranes, Lipid, Electrode, Biosensor, Surface- bound, Cells, Proteins, Membranes(Biology), Rhodopsin, Octylglucosides.
