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 produce 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.

Sers Intensity

A stable nanosilver solution was prepared, using PEG10000 as stabilizer and NaBH4 as reducer. In pH 6.6 Na2HPO4-NaH2PO4 buffer solution containing PEG10000 and NaCl, nanosilvers were aggregated to form the stable aggregated-nanosilvers (ANS) that could conjugate with 4-mercaptopyridine (MP) to produce an ANS-MP surface-enhanced resonance Raman scattering (SERRS) probe, which exhibited a strong SERS peak at 1097 cm-1. When cystine (Cy) concentration increased, the SERS intensity at 1097 cm-1 decreased linearly. In the optimal condition, the decreased SERRS intensity was linear to Cy concentration in the range of 5.0×10-9-1.4×10-7 mol/L, with a detection limit of 2.0×10-9 mol/L Cy.

In pH 6.5 Na2HPO4-NaH2PO4 buffer solution and in the presence of stable reagent PEG10000 and aggregation reagent NaCl, nanosilvers were aggregated to form stable aggregated-nanosilvers (ANS). The molecular probe of 4-mercaptopyridine (MP) adsorbed on the surface of ANS to form MP-ANS conjugates that produce strongest surface-enhanced resonance Raman scattering (SERRS) peak at 1097 cm-1. When Au(III) was added, the SERRS intensity at 1097 cm-1 decreased. The decreased SERRS intensity was linear to Au(III) concentration in the range of 5-50 ×10-10 mol/L, with a detection limit of 2.0×10-10 mol/L Au(III).

Citric Acid Buffer

In pH 6.6 Na2HPO4-citric acid buffer solution and in the presence of KCl, the nanosilver-labeled rabbit anti-hCG (Ag-RAhCG) was aggregated un-specifically to the aggregations. Upon addition of rhodamine 6G (RhG) molecular probe, it adsorb on the surface of Ag-RAhCG aggregations that exhibited the strongest surface-enhnaced resonance Raman scattering (SERRS) peak at 613 cm-1. In the optimal condition, the decreased SERRS intensity responds linearly with the concentration of hCG over 0.05-1.75 µg/mL. Based on this, a new and simple SERRS method has been proposed for the determination of hCG in serum samples, with satisfactory results.
