Abstract:

Surface plasmon resonance (SPR) sensing technology is widely used in biomedicine, pharmaceutical screening, clinical diagnosis, food safety, environmental pollution detection, and other fields. Because of the sensitivity of SPR systems to temperature, practical applications of SPR are limited. In this study, based on angle-modulation SPR, a temperature-controlling department is designed with a sensitivity of 497.8${^\circ}$/RIU (refractive index unit) and a 0.1 ℃ accuracy temperature in the range of 18$\sim$42 ℃. This SPR technology can be successfully used in various temperature changing liquid-crystal molecule systems. Results showed that the SPR signal had a good linear relationship with the temperature in the range of 25$\sim$41 ℃, with a correlation coefficient greater than 0.98.
