Chemical modification of the surfaces of silver nanoparticles: Synthesis of Janus particles

Abstract

Forming an ordered surface layer is possible together with the formation of Janus nanoparticles in the chemical modification of the surface of silver colloids. This is achieved via sorption of nanoparticles on the surface of chemically modified silica grafted with amine, followed by sequential treatment with modifier solutions and desorption of the final product. As a result of using such a synthetic procedure, a chemical modification of nanoparticles with two compounds on different sides is possible.
