The combination of surface-enhanced Raman spectroscopy (SERS) with near-infrared (NIR) excitation should be of considerable benefit for trace detection of biological and environmental samples. Enhancement factors for SERS of p-aminobenzoic acid (PABA) on silver/alumina, silver island, gold/alumina and gold island surfaces were determined using unenhanced FT-Raman spectra of PABA on glass and glass/alumina surfaces as references. The silver/alumina substrate provided the greatest enhancement factor, followed by silver island, gold/alumina and gold island substrates, respectively. An enhancement factor in excess of 106 for PABA on a silver/alumina substrate compares favourably with literature reports of similar systems at shorter wavelengths.
