Surface Plasmon Resonance (SPR) sensor has been studied in various fields such as biosensor because of its high sensitivity to surrounding refractive index changes. In this study, a novel far- and deep-ultraviolet (FUV and DUV, 150~300nm) SPR sensor has been developed by using aluminum thin film. The new SPR sensor may have high sensitivity.
In this study, by using our original attenuated total reflectance (ATR) FUV-DUV spectroscopy, we successfully measured SPR characteristic behaviors depending on the refractive index changes by putting various solvents on the aluminum thin film.
