Synthesis and comparison of gold nanoparticles coated with silicon, manganese and titanium dioxides

Abstract

The synthesized gold nanoparticles (50-60 nm) were coated with thin (1.5-8 nm) layers of silicon, manganese and titanium dioxides. The obtained three species of nanospheres were applied for the analysis of self-assembled monolayer of thiophenol by shell-isolated nanoparticle-enhanced Raman spectroscopy method. Detailed synthesis and comparison of the particle properties are provided in this report.
