SURFACE-ENHANCED RAMAN SPECTROSCOPY OF VIRION OF DARNA TRIMA GRANULOSIS VIRUS
茶刺蛾颗粒体病毒病毒粒子的表面增强拉曼散射(SERS)光谱研究

The surface - enhanced Raman Spectra of the Virion of Darna trima Granulosis Virus (DtGV) adsorbed on silver hydrosol were obtained and analysed. Both amino and carboxylate groups of the virion of DtGV were bound to silver hydrosol. The side-chains of Trp. Tyr and Phe residues were close to the silver surface, but the vibrations of side - chains of Trp residues were markedly enhanced. The enhanced characteristic of the virion of DtGV depended greatly on the pH of solution.
