摘要：

The coproporphyrin-I (CPI) behaves as a reducing agent for silver and gold metal ions and as stabilizing agent for the formed colloidal metallic nanoparticles. The peculiarity of silver and gold nanoparticles obtained in the reactions of monomeric form of CPI with their metal ions has been studied. The optical properties of the colloidal forms of these metals have been investigated by UV-Vis spectrophotometry, and their morphology by TEM and SEM measurements. The structures and the size distributions of Ag and An particles have been characterized and determined by computerized TEM images. (C) 2007 Elsevier Ltd. All rights reserved.
