Abstract

The various nitro polynuclear aromatic compounds, Including 1-nitropyrene, 9-nitroanthracene 2-nitronaphthalene, and 2-nitrofluorene have been investigated by use of the surface-enhanced Raman scattering (SERS) spectrometry technique. Silver-coated substrates consisting of latex spheres on glass and filter paper and prolate SlO2 posts on posts on quartz were used. The limit of detection of 1-nitropyrene was found to be 0.3 ng. The SERS signals were enhanced over conventional Raman signals by a factor of 5 X 10⁶ to 9 X 10⁶ for 1-nitropyrene adsorbed on various SERS-active substrates. The production and practicality of SERS-active substrates with glass, paper, and quartz supports are discussed.
