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