The Battelle Biological Spectroscopy Facility is currently studying the adsorption of blood proteins onto various surfaces using the combination of Fourier transform infrared spectroscopy (FT-IR) and attenuated total reflectance (ATR) optics. We have advanced our capabilities to study this phenomenon to the point where useful infrared spectra are obtained at 0.8-s intervals. This high-time resolution is helping to probe more accurately these important blood-surface interactions.
