摘要：

Surface-enhanced Raman scattering (SERS) -active polyvinyl alcohol films doped with Ag particles have been prepared by a counterdiffusion method. SERS spectra of CO2-3, SO2-3, and DNA bases have been observed by using the films. The films containing aggregated Ag particles are useful to observe SERS spectra of adsorbates. DNA bases (cytosine, uracil, thymine, guanine, and adenine) can be detected at a level of 10-8-10-9 M by this method. © 1993 Academic Press. All rights reserved.
