Synthesis and biological application of magnetite nanoparticles

Magnetite (Fe3O4) nanoparticles were prepared by chemical coprecipitation from a ferrous/ferric mixed salt-solution in the presence of PVP used as a stabilizer and without it. The resulting magnetite nanoparticles were characterized by X-ray powder diffraction (XRD) analysis and scanning electron mi...
