Surface-enhanced Raman spectrometry of triamterene on a silver substrate prepared by the nitric acid etching method.

Surface-enhanced Raman scattering (SERS) spectrometry of the diuretic drug triamterene is discussed. The SERS-active substrate used is a silver foil etched with nitric acid. The influence of solvent and sample doping method on sensivity, intercept and shape of the calibration graphs is discussed.
