Abstract

Although the surface Plasmon resonance (SPR) sensor is a mature technology, currently, the sample temperature needs to be carefully considered and controlled because SPR signals vary with temperature. This poses a large challenge in the applications where the sample temperature changes during measurement or an SPR sensor operates in different environmental temperatures. This paper proposes and experimentally demonstrates, for the first time to our knowledge, a solution to simultaneously measuring refractive index and temperature based on conventional SPR sensors, thus, not only requiring no temperature control/calibration during the measurement but also enabling SPR sensors for in-situ operations.
