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 coppe...
