Surface enhanced Raman spectroscopy (SERS) allows the detection of trace quantities of molecular species adsorbed onto a surface. The potential use of silver colloids as substrates for analytical SERS measurements is demonstrated. Detection limits and other analytical figures of merit for pyridine, p-aminobenzoic acid and p-nitrobenzoic acid are presented.
