A gold monolayer film and cysteine layer-by-layer self-assemble onto modified glasses, and through the use of optical waveguide spectroscopy (OWGS) and a dynamic SERS technique for the first time to study the dynamic generation process of the Meisenheimer complex between TNT and cysteine. This strategy can detect TNT down to 1 nM with high sensitivity and selectivity.
