Abstract

 Pristine crystalline superparamagnetic Nanoparticles (SPNs) 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, VSM, DLS and FE-SEM. The SPNs were further grafted by poly(N-vinyl-2-pyrrolidone) during their deposition process. The PVP-grafting via electrochemical route was confirmed by IR, DSC-TGA and DLS analyses. The analyses results confirmed the proper phase (i. e. pristine magnetite), size (about 10 nm) and excellent super-paramagnetic nature (Ms=48. 57emu g– 1, Mr≈ 0. 038 emu g– 1 and Ce~1. 35G) of the prepared PVP-grafted Fe3O4 Nanoparticles for biomedical applications.
