Photon correlation spectroscopy as a tool of characterization of SERS-active systems based on Ag sols

Abstract Photon correlation spectroscopy and microelectrophoresis are investigated as tools to characterize SERS-active systems. Mutual relations of SERS spectra, UV/vis spectra, hydrodynamic size and zeta-potential are studied for systems based on Ag sol and two different adsorbates (2,2′-bipyridine and pefloxacin).
