A. Ruperez et Jj. Laserna, SOLVENT EFFECTS ON SURFACE-ENHANCED RAMAN ACTIVITY OF ADSORBATES ON COLLOIDAL SILVER, Applied spectroscopy, 48(2), 1994, pp. 219-223
Surface-enhanced Raman spectrometry of a variety of drugs on colloidal
silver is reported. Solvent effects on the Raman activity of adsorbat
es are discussed in terms of coadsorption and replacement kinetics at
the silver surface. It is shown that the number of analytes amenable t
o SER spectrometry and the quality of the spectra can be improved by o
ptimizing the solvent for the adsorbate under study. The influences of
solvent on sensitivity, linear range of response, and shape of the ca
libration graph are discussed.
