中文摘要	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 N-2 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, DI-S and VSM.
