摘要：
present theoretical study exhibits the possibility of achieving an incredibly highly sensitive surface plasmon resonance based biosensor comprising a Cu-Pt bimetallic layer and a BlueP/WS2 hybrid nanostructure for an angular interrogation method. Based on the Transfer matrix method, the thickness of Cu and Pt and the number of BlueP/WS2 layers are optimized to obtain the best possible sensitivity and FOM. A well-optimized Cu-Pt-BlueP/WS2 hybrid structure generates sensitivity as high as 502 & DEG;/RIU with an FOM of 128.7RIU-1. Such a sensor is handy for detecting biomolecules.
