SERS is widely used as a detection procedure in various analytical applications due to high sensitivity. One of the stages in the development of such methods is the identification of the compound to be quantified using reference spectra. High-intensity reference SERS spectra without extraneous bands are obtained in a wide spectral interval for an important analyte (2,3-diaminophenazine), the Raman scattering of which is enhanced by aggregated hydroxylamine sols of silver nanoparticles.
