In this study, a facile route is described for the synthesis of stabilizer-free gold nanoparticles (AuNPs) by the sonochemical reduction of the aqueous solution of HAuCl_4 using a 490-kHz sonochemical reactor. It was found that AuNPs synthesized by sonochemical process exhibited higher surface-enhanced Raman scattering (SERS) activities compared to those prepared by prepared by the more conventional wet method with trisodium citrate. It was also found that the colour of AuNPs solution was changed from pink to blue sky, and the absorption band shifted to long wavelength after the addition of trace Se (IV) implying its prospects to be as a label-free, colorimetric sensor for Se (IV).
