Abstract:
Metal-carrying polysaccharides based on chitosan and a collagen-chitosan composite (collachit) were obtained by modifying polymers by Au and Fe nanoparticles, which were prepared via metal vapor synthesis. Gold nanoparticles were synthesized using organosols with triethylamine; Fe nanoparticles, using the thermally labile bis(arene) complex, viz., bis(toluene)iron. The composition and structures of the resulting materials were studied by Mössbauer spectroscopy, XPS, and X-ray diagnostics using synchrotron radiation. Particles of Au (7.5–10 nm) and Fe (6–7 nm) were detected in metallopolymers by X-ray powder diffraction. The XPS analysis of gold-containing nanocomposites showed two states of Au4f. One of them is metallic with the binding energy of the Au4f7/2 peak equal to 83.8 eV, and another one is partially oxidized with the binding energy of the Au4f7/2 peak equal to 85.5 eV; the atomic concentrations of the two states are 16% and 84%, respectively. A comparative analysis of the Mössbauer spectra of iron-containing chitosan and collachit demonstrated that these two samples have similar structures. Thus, iron is present as a metallic phase (−30%) and a superparamagnetic gamma-iron oxide (−74%). The size of gamma-iron oxide nanoclusters in the samples can be estimated at −6–8 nm.
