A surface plasmon resonance based biosensor consisting of SF10 prism, silicon layer, gold thin film and MoS2 enhanced nanosheet is presented. We systematically investigated the SPR reflectivity and resonance angle through the transfer matrix method. Furthermore, with the optimized thickness of gold,...
