Dextran Capped Gd^3+-doped Fe_3O_4 Nanoparticles: Electrochemical Synthesis and Characterization

In this work, we report dextran capped gd^3+-doped fe_3o_4 nanoparticles prepared through a novel and facile electrodeposition method. the properties of the nanoparticles such as size, percentage of dextran capped layer, crystallinity, and magnetic properties were evaluated through xrd, ir, fe-sem, vsm and dsc-tga techniques. the electrodeposited ions showed saturation magnetization of 18.02 emu g^–1, remanent magnetization of 0.063 emu g^–1 and coercivity of 2.59 g, and have superparamagnetic nature. based on the obtained results, the developed electrochemical synthesis method is proposed as an easy route for the fabrication of superparamagnetic polymer-grafted and metal-ion doped iron oxide nanoparticles.
