Theoretical analysis of a high-performance surface plasmon resonance biosensor using BlueP/WS2 over Cu-Pt bimetallic layer

Abstract

The present theoretical study exhibits the possibility of achieving extremely high sensitive surface plasmon resonance based biosensor comprising of Cu-Pt bimetallic layer and BlueP/WS2 hybrid nanostructure for angular interrogation method. Based of Transfer matrix method thickness of Cu and Pt as well as the number of BlueP/WS2 layer is optimized to obtain the best possible sensitivity and FOM. The well optimized Cu-Pt-BlueP/WS2 hybridstructure is found to generate sensitivity as high as 502°/RIU with FOM as 128.7RIU-1 such sensor is highly useful for detecting biomolecules.
