Abstract
Use of the noble metal nanoparticles in the surface-enhanced resonance Raman spectroscopy (SERRS) is a significant part the measurement. These nanoparticles are often used for SERRS measurements of silver nanoparticles prepared by reduction methods. From the literature it is obvious that the most popular methods of preparation of Ag nanoparticles are procedures which are using the chemical reduction and/or laser ablation. In this paper we discuss the comparison of SERRS spectra of water-soluble porphyrins (TTMAPP and TMPyP) in systems with Ag nanoparticles prepared by chemical reduction with sodium borohydride, sodium citrate and glucose. The comparison of different systems gives insight into the option of suitableility of using of nanoparticles with various surface ions in the production of different spectral forms of chosen porphyrins in dependence on their structures.
