Combined Electrochemistry and Surface-Enhanced Infrared Absorption Spectroscopy of Gramicidin A Incorporated into Tethered Bilayer Lipid Membranes

Support from the support: Tethered bilayer lipid membranes containing the cation-channel-forming peptide gramicidin A were assembled on nanostructured Au films. The combination of surface-enhanced infrared absorption (SEIRA) and electrochemical impedance spectroscopy (EIS) was used for the in situ structural and functional characterization of gramicidin A in the same device.
