Surface-enhanced resonance Raman scattering of porphyrins on gold nanoparticles attached to silanized glass plates.
Biopolymers. 2006 Jul; 82(4):390-3.B

Abstract

Surface-enhanced resonance Raman scattering (SERRS) spectra of cationic 5,10,15,20-tetrakis(1-methyl-4-pyridyl) porphyrin (TMPyP) and anionic 5,10,15,20-tetrakis(4-sulfonatophenyl) porphyrin (TSPP) were measured from gold surfaces prepared by attaching citrate-reduced colloidal nanoparticles to glass slides silanized by 3-aminopropyltrimethoxysilane. SERRS spectra of both porphyrins obtained in a large concentration range (1 x 10(-4) to 1 x 10(-7)M) of primary solution do not show any sign of porphyrin metalation or perturbation of its native structure. Optimal adsorption time (15-20 min) and covering concentration limit (lower than 1 x 10(-5)M) of porphyrins have been estimated from the concentration and soaking time dependences of SERRS spectra.
