摘　　要：A network structure surface-enhanced Raman scattering(SERS)-active substrate is fabricated by adding Ag sol dropwise on adhesive tape.Scanning electron microscope(SEM) is employed to characterize the structure of the as-prepared substrate.The substrate shows great SERS enhancement ability and good uniformity by using p-aminothiophenol(PATP) as probe molecules.The detection of crystal violet(CV) in aqueous solution is demonstrated,and the detection limit is as low as 10-12M with the aid of the substrate.The results indicate that the proposed method is a potential approach for the fabrication of SERS substrates.A network structure sttrface-enhanced Raman scattering （SERS）-active substrate is fabricatea oy adding Ag sol dropwise on adhesive tape. Scanning electron microscope （SEM） is employed to characterize the strucroxe of the as-prepared substrate. The substrate shows great SERS enhancement ability and good uniformity by using p-aminothiophenol （PATP） as probe molecules. The detection of crystal violet （CV） in aqueous solution is demonstrated, and the detection limit is as low as 10 12 M with the aid of the substrate. The results indicate that the proposed method is a potential approach for the fabrication of SERS substrates.
