MoS2 based dual gate MOSFET as ultra-sensitive SARs-CoV-2 biosensor for rapid screening of respiratory syndrome
In this letter, an attempt for rapid detection of biomarkers for SARs-CoV-2 virus is initiated for
the first time, employing MoS 2= based dual-gate mosfet with embedded nanogap in the
gate dielectric. Based on the spike, envelope, and DNA proteins of the virus, a deep analysis
of the device performance in terms of transfer characteristics I on/I off ratio is performed
using SILVACO ATLAS TCAD by considering the dielectric constant equivalent of the virus
proteins as κ= 4, 10, 12 and with variation of DNA charge densities as− 2× 10 12 Ccm− 2 to+ …
