| Abstract: Monodispersed Fe3O4-Dextran nano-particles were prepared by chemical co-deposition with average diameter of 16 nm, and a core of diameter of 5.5 nm for Fe3O4 with a shell of thickness 5 nm for Dextran. The results of magnetic property determination show that: they have a good magnetization of 76 emu·g-1 which is increased by a factor of 49%. As compared with 51 emu·g-1 for the material obtained without the addition of coordination compound in the processing. |
| Keywords: Fe3O4-dextran monodisperse coordination compound superparamagnetic |
