Design, Synthesis and Characterization of Properties Dextran-Coated Magnetic Nanoparticles

In this work, we study the preparation and properties of bio-compatible magnetic nanoparticles. Iron oxides (Fe3O4 and γ-Fe2O3 form) magnetic particles, are the most widely studied in the medical, pharmaceutical and biotechnological areas. Magnetic nanoparticles have attracted attention because of their current and potential usefulness as contrast agents for magnetic resonance imaging (MRI) or colloidal mediators for cancer magnetic hyperthermia. In our work dextran coated iron oxide nanoparticles, in a 1:2 ratio of Fe (II) and Fe (III) salt in the HCl solution with of NaOH at a given temperature synthesis, purification and nanoparticles characterization covers. The resulting nanoparticles were characterized by FTIR, XRD, DSC, DTA and TGA analyzes
