Abstract
Surface-Enhanced Raman Scattering (SERS) caused by Localized Surface Plasmon Resonance of gold nanoparticles is one of candidates of biosensing material application for organic molecular measurement with high sensitivity and selectivity. In this study, we've aimed to find out the gold nanoparticles with excellent SERS properties and figure out the SERS mechanism by preparing gold nanoparticles with a lot of branches. In this report, different types of gold nanoparticles were synthesized and their shapes and SERS spectra were investigated.
