Effect of temperature on the incident angle-dependence of the sensitivity for surface plasmon resonance spectroscopy

Abstract

The recent work reporting the observation of the increase in sensitivity for surface plasmon resonance (SPR) spectroscopy at smaller incident angles, is further studied with variation in the temperature of the SPR sensor. Using a simple theoretical model established previously, it is found that in spite of the increase in damping for the resonance at higher temperatures, the recent finding of the increase of sensitivity with decrease in incident angles remains valid.
