Quercetin (QUC), one of the most common flavonols widely distributed in the plant kingdom, is of interest both as a dye and biologically active molecule. The surface-enhanced Raman scattering spectrum of QUC has been already reported in a number of previous papers. However, a deeper interpretation of the chemical processes developed by QUC on metal nanoparticles is discussed here for the first time. In addition, characteristic spectral assignment for the species recognized under different experimental conditions has been conducted.
