Synthesis of Metallic Janus Nanoparticles by Aerosol Spraying

Resumo

A modified method for synthesizing metallic Janus nanoparticles that consists in the evaporation of droplets of colloidal solutions of metal nanoparticles in ethyl alcohol deposited on a silicon substrate, has been developed. The structure of the synthesized silver Janus nanoparticles has been determined using scanning electron microscopy and atomic-force microscopy. It has been shown that the developed modified method allows the synthesis of crescent-shaped nanoparticles with an adjustable size.
