| Hybrid bilayer membranes (HBMs), consisting of a lipid monolayer atop a thiolipid monolayer self-assembled onto a metal-coated, nanostructured surface, are characterized via in situ Raman spectroscopy. The HBM provides a useful mimic for studying the structure and function of cell membranes and their constituents. The nanostructured support enhances the Raman scattering cross-section enabling the acquisition of in situ Raman signal from the HBM as a complement to in situ infrared vibrational spectroscopic studies. The structures of a variety of supported lipid bilayers on metallic nanostructures will be presented. These HBMs also permit the incorporation and orientation of membrane polypeptides, such as gramicidin, for structural studies. |
