In this paper, we developed a novel and facile electrodeposition method for Mn2+ doped superparamagnetic iron oxide nanoparticles (Mn-SPIONs) in both bare and poly(vinylpyrrolidone) (PVP) capped forms (i.e. bare Mn-SPIONs and PVP capped Mn-SPIONs). The magnetite crystal structure, uniform spherical particle morphologies, nanometer size, Mn2+ cations incorporation and PVP surface coat were confirmed...
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...
