Abstract:

Silver nanoparticles are well known for their unique optical properties in the visible spectral region. They can serve as efficient enhancers of Raman scattering of adsorbed molecules. Porphyrins are biologically and medically important species. In order to detect their native forms and avoid self-aggregation for instance, it is necessary to work at low porphyrin concentrations. In this contribution, it is shown that using silver nanoparticles generated by ?green? methods the porphyrin concentrations as low as 10 -13 M can be reached repeatedly in aqueous solutions
