Abstract
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.
摘要
金单层膜和半胱氨酸通过层层自组装到修饰的玻璃上，并首次使用光波导光谱（OWGS）和动态 SERS 技术研究 TNT 与半胱氨酸之间的 Meisenheimer 复合物的动态生成过程。该策略可以高灵敏度和选择性地检测低至 1 nM 的 TNT。
