SERS Study of Malachite Green on Silver Nanocaps Arrays

Abstract:

In this paper Ag nanocaps arrays were fabricated with a seed-mediated growth method by depositing Ag films on top of self-assembly close-packed monolayer of SiO2 nanoparticles. Their surface morphologies and optical properties were characterized using TEM, SEM and UV-Vis spectroscopy. Malachite green (MG) was chosen as analyte, the Surface-enhanced Raman Scattering (SERS) spectra of MG adsorbed on Ag nanocaps arrays were investigated. The enhancement factor was estimated to be as large as 4.5×10⁹. These results revealed that these Ag nanostructures are promising for SERS applications in trace measurement and analysis of biological molecules.
