Zinc Oxide/Ag Water-Gated Field-Effect Transistor Coupled with Surface-Enhanced Raman Scattering for Indigo Dye Detection

Water-gated field-effect transistors (WGFETs) based on a solution-processed ZnO–Ag composite are developed as a complementary electrical–spectroscopic sensing platform, combining electrical detection of indigo in aqueous media with SERS-based molecular identification on the same ZnO–Ag active layer. The resulting WGFET...
