二硒化铂(PtSe2)具有与石墨烯和磷烯相似的结构，其特殊的光电性质在快速发展的二维材料中引起了人们的极大关注。用传输矩阵法研究了PtSe2表面等离子体共振(SPR)传感器。仿真结果表明，所设计的PtSe2生化传感器具有检测分析的能力。结果表明，只有银膜和金膜生化传感器的灵敏度分别为118°/RIU和130°/RIU，而PtSe2基生化传感器的灵敏度高达162°/RIU(银膜)和165°/RIU(Au膜)。PtSe2具有不同的生物传感器灵敏度，这表明这种2D材料可以适应SPR传感器的特性。
The extraordinary optoelectronic properties of platinum diselenide (PtSe2), whose structure is similar to graphene and phosphorene, has attracted great attention in new rapidly developed two-dimensional (2D) materials beyond the other 2D material family members. We have investigated the surface plasmon resonance (SPR) sensors through PtSe2 with the transfer matrix method. The simulation results show that the anticipated PtSe2 biochemical sensors have the ability to detect analytic. It is evident that only the sensitivities of Ag or Au film biochemical sensors were observed at 118°/RIU (refractive index unit) and 130°/RIU, whereas the sensitivities of the PtSe2-based biochemical sensors reached as high as 162°/RIU (Ag film) and 165°/RIU (Au film). The diverse biosensor sensitivities with PtSe2 suggest that this kind of 2D material can adapt SPR sensor properties.
