  • By means of chemical co-deposition method in which added Ferric citrate and Ferrous Gluconate, Fe3O4-Dextran composite nano-particles having average diameter 26 nm, was obtained. The particles had a core of diameter 4.1 nm Fe3O4 with a shell of thickness 11 nm Dextran. In the experiment the critical structure of Fe3O4 inorganic particles abstained without N2 protection had no changes. From the result, it can be proven that organic salt has antioxidation properties and the composite particles have superparamagnetic whose good magnetization is 52 emu/g at 300 K, and 63 emu/g at 5 K. The structure, pattern diameter and magnetic properties of the Fe3O4-Dextran composite particles were examined by means of TEM, XRD, DLS and VSM.

Abstract: By means of chemical co-deposition method in which added Ferric citrate and Ferrous Gluconate, Fe3O4-Dextran composite nano-particles having average diameter 26 nm, was obtained. The particles had a core of diameter 4.1 nm Fe3O4 with a shell of thickness 11 nm Dextran. In the experiment the critical structure of Fe3O4 inorganic particles abstained without N2 protection had no changes. From the result, it can be proven that organic salt has antioxidation properties and the composite particles have superparamagnetic whose good magnetization is 52 emu/g at 300 K, and 63 emu/g at 5 K. The structure, pattern diameter and magnetic properties of the Fe3O4-Dextran composite particles were examined by means of TEM, XRD, DLS and VSM.
