Topological insulator overlayer to enhance the sensitivity and detection limit of surface plasmon resonance sensor
Surface plasmon resonance (SPR) sensors have been applied in a wide range of applications for real-time and label-free detection. In this article, by covering the topological insulators nanosheets on the surface of the noble metal (Au), the sensitivity of the SPR sensor is greatly enhanced because o...
