WS<sub>2</sub>/Si<sub>3</sub>N<sub>4</sub>-Based Biosensor for Low-Concentration Coronavirus Detection

WS<sub>2</sub>/Si<sub>3</sub>N<sub>4</sub>-Based Biosensor for Low-Concentration Coronavirus Detection

This study presents the optimization of two SPR biosensors, Sys<sub>3</sub> and Sys<sub>5</sub>, for SARS-CoV-2 detection at concentrations of 0.01–100 nM. Sys<sub>3</sub>, with a 55 nm silver layer, a 13 nm silicon nitride layer, and a 10 nm ssDNA layer, achieved...
