Templateless Synthesis of Organosilica Nanotoroids and Creation of Core/Shell Plasmonic Structures Thereon

Аннотация

It has been shown for the first time that nanosized organosilica toroids can be formed via hydrolytic condensation of (γ-mercaptopropyl)trimethoxysilane in an alkaline medium. It has been found that such toroids may be used as “nuclei” for the synthesis of plasmonic composite nanoparticles with a core/shell structure.
