Metal Nanoparticles Protected with Monolayers: Synthetic Methods
Read full article onlineFull Article
The basic synthetic methods of monolayer-protected metal nanoparticles including Au, Ag, Cu, Pt, and Pd particles are presented. (There is also an article on “Metal Nanoparticles Protected with Monolayers: Applications for Chemical Vapor Sensing and Gas Chromatography,” which explores the sorptive properties in depth.) This entry introduces the fundamentals about protective monolayers from various organic compounds containing reactive functional groups such as thiol, disulfide, sulfide, thiosulfate, xanthate, ammonium, amine, phosphine, phosphine oxide, carboxylate, selenide, isocyanide, etc.
