Abstract

Attenuated total reflectance Fourier transform infrared spectroscopy is used to monitor the adsorption of 100 nm 1,2-dipalmitoyl-sn-glycero-3- phosphocholine (DPPC) phospholipid vesicles to the surfaces of Ge, electrolessly deposited Au, and a well formed self-assembled monolayer of 1-octadecanethiol. The interaction of DPPC vesicles in solution with these different surfaces yields distinctly different surface structures: intact DPPC vesicles on Ge, a supported phospholipid bilayer on an electrolessly deposited Au surface, and a phospholipid monolayer onto the hydrophobic self-assembled monolayer. IR peak position, bandwidth, and intensity are used to confirm structure formation and quantitation of the amount of lipid that desorbs during film formation.
