A gold nanoparticle chemically modified gold electrode for the determination of surfactants

A chemically modified electrode (CME) bearing gold nanoparticles assembled onto a gold electrode via a 1,4-benzenedimethanethiol SAM bridge has been successfully employed for the determination of surfactants in solution, using a redox probe and exploiting the tendency of surfactants to be adhere to the high-energy nanoparticles' surface.
