Abstract
The adsorption of the acridine derivative drugs Quinacrine (QA) and 9-aminoacridine (9AA) on silver surfaces was comparatively studied by surface-enhanced Raman spectroscopy (SERS). The effects of the excitation wavelength, pH and chloride concentration on the SERS spectra were investigated. The analysis of the Raman spectra reveals that each drug is able to interact with the metal surface through different mechanisms of adsorption. This is related to the distinct chemical structure of both drugs. The results shown in this work demonstrate the existence of different adsorption sites on the metal surface.
