SE(R)RS microspectroscopy of porphyrins on immobilized Au nanoparticles: Testing spectral sensitivity and reproducibility
Original language description
Although surface-enhanced (resonance) Raman scattering SE(R)RS spectroscopy is currently employed as a (bio)analytical technique, designing and optimizing of cheaply and easily available SERS-active substrates are still in progress. In this paper, we tested SERS substrates prepared by immobilization of Au colloidal nanoparticles via aminosilane on glass from the point of view of their spectral sensitivity and reproducibility. This preparation procedure is easy, cheap and provides uniform SERS substrateson a large scale. We measured SE(R)RS spectra of free-base cationic 5,10,15,20-tetrakis(1-methyl-4-pyridyl)porphyrin (TMPyP) as a testing biomolecule using a confocal Raman microspectrometer and two excitation wavelengths (514.5 and 632.8 nm). SERS microspectroscopy had several advantages in comparison to macro-Raman technique: namely the possibility of spectral mapping over the surface, shorter collection times and the absence of strong Raman bands from the glass support.
