COLLOIDAL GOLD NANOPARTICLE SOLUTIONS FOR SURFACE ENHANCED RAMAN SCATTERING

摘要

The use of colloidal gold nanoparticle solutions to enhance Raman scattering from analyte molecules of interest that can detect molecules present at concentrations from 0.001 ppm to 10 ppm in pure solvent and wherein the synthesis of the gold nanoparticles is tailored to achieve maximum enhancement from analytes with 785 nm laser excitation is disclosed.
