High sensitive self-assembled monolayer modified solid mounted resonator for organophosphate vapor detection

▶ We present a novel design of the electro-acoustic thin film resonators based chemical sensors for trace organophosphate vapor detection. ▶ Our proposed sensor consisted of a solid mounted resonator working at 2.38 GHz and a Cu2+/11-mercaptoundecanoic acid self-assembled monolayer. ▶ Our proposed sensor can yield a rapid, sensitive, reversible and reproducible response to nerve-agent stimulant (DMMP) vapor.
