Surface plasmon resonance biosensors for SARS-CoV-2 sensing: The role of silicon nitride and graphene

Surface plasmon resonance biosensors for SARS-CoV-2 sensing: The role of silicon nitride and graphene

We present a systematic optimization and analysis of SPR biosensors, focusing on the influence of design parameters such as silver (Ag), silicon nitride (Si₃N₄), graphene, and ssDNA layer thicknesses. Two configurations, Sys₃ and Sys₅, were developed and numerically evaluated under varying SARS-CoV-...
