This work shows comparative analysis of surface-enhanced Raman scattering (SERS) activity of gold nanoparticles fabricated by chemical synthesis and laser ablation methods. The gold nanoparticles prepared by laser ablation (Au-LA) are more effective for SERS than those prepared chemically (Au-citr). The “analyte on Au film” configuration allows obtaining enhancement of Raman scattering up to 104 in case of Au-LA nanoparticles and up to 102 in case of Au-citr. Also the “sandwich” configuration for Au-LA gives additional enhancement of SERS up to two times, and for Au-citr up to one order, that is consistent with theoretical calculations.
