A surface-enhanced resonance Raman scattering method for the determination of trace crystal violet on colloidal Au nanoparticle substrate
Colloidal Au nanoparticles as active substrate for surface-enhanced resonance Raman scattering(SERRS) were prepared by the trisodium citrate-reduced procedure.In pH 6.6 Na2HPO4-NaH2PO4 buffer solution and in the presence of aggregation reagent NaCl,nanogolds were aggregated to form stable aggregated-nanogolds (ANG).The crystal violet (CV) adsorbed on the surface of ANG to form CV-ANG conjugates that prodnce strongest surface-enhanced resonance Raman scattering peak at 1616 cm-1.In the optimal condition,the SERRS intensity at 1616 cm-1 was linear to the CV concentration in the range of 2.5×10-8-1.75×10-7 mol/L,a surface-enhanced resonance Raman scattering assay was set up for detection of trace CV,with good selectivity.
