Abstract
An instrument has been developed to acquire polarized attenuated total internal reflection (ATIR) mid-IR spectra of supported monomolecular films in situ at the lipid/water (L/W) interface. The monolayer film is applied to the treated surface of a trapezoidal germanium crystal as it is immersed into the subphase of a specially designed Langmuir-Blodgett trough. This approach offers several advantages over the study of monolayer films at the air/water (A/W) interface by external reflection techniques, including (1) an improved signal throughput and multiple reflections, both contributing to an improved signal-to-noise (S/N) ratio; (2) versatility with respect to the chemical nature of the surface; and (3) the ability to use standard spectral subtraction methods to compensate for absorption of the aqueous subphase. The enhanced sensitivity of this approach facilitates the study of in situ interactions of peptides with fully hydrated lipid membrane surfaces.
