Abstract

We have constructed a new system of narrow gap infrared reflection absorption spectroscopy (NG-IRRAS) for solid-solution interface biomaterials. A sample solution is confined in a narrow space between the CaF₂ prism and the substrate surface. The sample holder is specially designed to keep the narrow space constant during the measurement process. Absorption spectra of the solution phase immunoglobulin G (IgG) and the solid-solution interface IgG covalently bonded to the carboxyl-terminated self-assembled monolayer on the gold surface have been clearly observed with good reproducibility. Noticeable molecular conformation change induced by adsorption was not observed.
