Paper Abstract

In this paper, the Raman spectra of the cancer nude mouse serum were measured using surface-enhanced Raman scattering (SERS) with the silver colloid substrate. The result indicated that the SERS spectra of the serum increased several peaks compared with conventional Raman spectra. More ever, these peaks were so crucial for analysis of the serum component and structure so that the information of the protein, carbohydrate, lipid and other trace amounts component could be analyzed through SERS spectra. Therefore, SERS technique is reliably used to compare relative intensity shifts and to investigate the adsorption of biological molecular proteins on Ag nanoparticles.
