| Abstract: | A series of posibile factors that could improve the sensitivity of Surface-enhanced Raman Scattering(SERS) were investigated.The SERS intensity of RhodamineB(RhB),a highly fluorescent dye,was powerfully enhanced by using proper silver colloid system and adding chlorion into.Its SERS enhancement factor can be 1013.The prospects of applying of the method for biology molecules,the liability and availability of new method also were discussed. |
