e report the synthesis in water of colloidal silver nanoparticles (AgNP) with catalytic activity using a Gemini lipoamino acid surfactant derived from cystine above its critical micellar concentration as a capping agent. The Gemini surfactant interacts with the metal surface mainly in a monodentate vertical mode through the carboxylate and amide groups preserving intact the disulfide bond. These nanoparticles presented an excellent catalytic performance in the seed-mediated synthesis of AgNP and the reduction of p-nitrophenol.
