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 nanoparticleenhanced Raman spectroscopy method. Detailed synthesis and comparison of the particle properties are provided in this report.
