Pure crystalline superparamagnetic iron oxide nanoparticles (SPIONs) of magnetite (Fe3O4) were prepared from an additive-free aqueous solution of iron(III) nitrate salt though a novel one-pot electro-deposition method. The prepared nanoparticles were characterized by XRD, IR and TEM. The SPIONs were further coated by poly(N-vinyl-2-pyrrolidone) during their deposition process. The coating of PVP on SPIONs was confirmed by FT-IR, DSC-TGA and DLS analyses. The proposed electrochemical route can be concluded as a great routine for the preparation of polymer-coated SPIONs for biomedical applications.
