ResumoThe production, morphology, and optical properties of silver-coated filter paper as a new active substrate for surface-enhanced Raman spectrometry (SERS) are reported. The procedure involves a simple, one-stage reduction of filter-paper-supported silver nitrate with sodium tetrahydroborate. Intense and reproducible spectra of a variety of ionic and molecular adsorbates including p-aminobenzoic acid, acridine, 9-aminoacridine, 2-aminoanthracene, 6-nitroquinoline and 5-aminoquinoline are obtained. Simplicity, low cost, speed and availability are salient features of the substrate, which extend the applicability of the SERS technique to more practical situations.
