Abstract
The analytical potential of a new spectrochemical method based on surface-enhanced Raman spectrometry (SERS) on silver-spheres-coated substrates is presented for the first time in this work. A new method for preparing SERS-active substrate using submicron size silver-coated spheres deposited on filter paper substrates is described in detail. The analytical figures of merit and limitations of the technique are discussed. The detection limits for several organic compounds such as carbazole, 1-aminopyrene, and benzoic acid are 0.2, 1.4, and 0.3 ng, respectively. The results indicate that SERS shows great promise as a useful analytical tool for trace organic analysis.
