COPPER-CHITOSAN NANOCOMPOSITES: METAL VAPOR SYNTHESIS, SPECTROSCOPIC CHARACTERIZATION AND ANTIFUNGAL ACTIVITY
Abstract
New hybrid materials based on copper nanoparticles stabilized in an ultimately biocompatible chitosan matrix were prepared via metal vapor synthesis. Transmission electron microscopy shows that the particles have predominantly spherical form, polydisperse character, the mean diameter about 2-4 nm and a rather uniform distribution in the chitosan matrice. X-ray photoelectron spectroscopy of Cu-carrying chitosan powder obtained by impregnation of chitosan powder with Cu-acetone organosol indicated two oxidized copper states on the surface. Cu2+ ? Cu+ amounts calculated from the Cu 2p spectra were 2.6 and 6.0%, respectively. The structure of the materials was studied using X-ray techniques. The antifungal activity of the copperchitosan nanocomposites against the linear growth of pathogenic fungi Fusarium solani and Macrophomina phaseolina was evaluated in vitro and their effects on hyphal growth were evaluated. The results show that the copper-chitosan nanocomposites synthesized via metal vapor synthesis with acetone as intermediate nanoparticle stabilizer are effecient in inhibiting growth of Fusarium solani and Macrophomina phaseolina fungal hyphae.
