•Fe3O4 nanoparticles were successfully prepared in aqueous medium.•A new platform for surface coating of SPIONs was established.•In situ coating of Fe3O4 nanoparticles with PVP was achieved.•PVP coated SPIONs have proper size and magnetic properties.
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 electrodeposition 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.
