Abstract
We report a spectroscopic technique that combines the Fourier-Transform Infrared Spectroscopy with the Surface Plasmon Resonance. This tool enables sensitive infrared spectroscopy of liquid and solid objects in the attenuated total reflectance mode. The FTIR-SPR technique is similar to FTIR-ATR technique but has higher sensitivity due to resonance amplification of the surface electric field. The label-free FTIR-SPR technique is especially advantageous for living cell studies since it combines spectroscopic information inherent to FTIR with structural information provided by the Surface Plasmon Resonance. We discuss the FTIR-SPR technique for label-free studies of cell sedimentation and spreading on substrate and for surface plasmon spectroscopy.
