Professor Department of Physics University of Texas at Arlington


Since the realization of the surface plasmon excitations (SPEs) in the 1950s1, the subject matter continues to be of significant interest and has led to the development of surface plasmon resonance (SPR) sensors for biological, chemical, and physical applications. In view of an increasing demand for improvements in the sensitivity and resolution of SPR based sensors, numerous SPR sensor structures using single metal, bimetal, and waveguide-coupled architectures have been proposed. In collaboration with UTA’s Nanotechnology Research Center, Shimadzu Institute, we have undertaken investigations of the effects of the fabrication parameters on SPR sensor performance. I will discuss the basic physics of SPR, relevant experimental techniques, and present selected examples from our work.2-7
