Electrically configurable SERS-FET for the highly sensitive and selective detection of molecules

Abstract

Surface-enhanced Raman scattering (SERS) is a spectrum detection technique with extremely high sensitivity and detectivity. However, the performance of the SERS detection in practical scenario is always degraded by the...

A WOx/MoOx hybrid oxide based SERS FET and investigation on its tunable SERS performance

“…20 In the end, SERS detection in practical applications usually encounters various interfering molecules in the samples; however, the conventional noble-metal-based SERS substrate always enhances the Raman spectra of all molecules simultaneously. 28 As a consequence, the Raman spectra of the interested molecules are submerged under the Raman spectra of non-interested molecules. In view of the above dilemmas, the novel SERS substrate with the ability of efficiently and actively tunable SERS performance has attracted enormous interest.…”
