Title: Surface-Enhanced Raman Spectroscopy via Gold Nanostars
Published: September 28, 2008
Abstract: Anisotropic metallic nanoparticles have unique optical properties, which lend them to applications such as Surface Enhanced Raman Spectroscopy (SERS). Branched and star-shaped gold nanoparticles have been prepared in aqueous phase by seed-mediated growth methos by using 10nm, commercially available, gold colloid solution. Characterization of the nanostars was performed via UV-Vis absorption spectroscopy and Transmission Electron Microscopy (TEM) showing unprecedented nanostructures. SERS measurements for 2-Mercaptopyridine adsorbed on aggregated gold nanostars show a larger enhancement than 2-MPy on spherical nanoparticles of the similar size.
