  • We studied to prepare subshates for Surface-Enhance Raman Scattering (SERS). Gold nanoparticles were produced by laser ablation of gold plate in ethanol. The average size of gold nanoparticles is l3nm. The gold nanoparticle colloid was allowed to dry on a silicon wafer to prepare SERS substrate. Using the gold nanoparticle substrates we could obtain SERS spectrum of Rhodamine 6G molecules adsorbed on gold nanoparticles. The Raman signal was enhanced strongly by our SERS subshate. This result demonstrates that the metal nanoparticles synthesized by laser ablation in clean liquid can be used to prepare SERS substrate for molecular detection in our laboratory.
