Rapid Detection of Clenbuterol Using Au Nanoparticles Base on Surface-Enhanced Raman Scattering

Au nanoparticles (AuNPs) colloid with a good dispersion was synthesized by chemical reduction method and their properties as surface-enhanced Raman scattering substrate were examined. The average particle size obtained is about 80 nm and the UV-vis characteristic absorption peak appears at 528 nm, which is a typical characteristic absorption peak of the AuNPs. The AuNPs colloid was used as substrate to detect Clenbuterol, and the lowest detection limit is 1mg/L. The result shows that the Au nanoparticles have a good surface-enhanced Raman scattering activity.
