Water-soluble superparamagnetic Fe3O4nanoparticles with an average diameter of 9.5±1.7nm were synthesized by thermal decomposition of Fe(acac)3in MPEG. MPEG was used as solvent, reducing agent, and modifying agent in this reaction. An obvious advantage of this approach is that no further reducing agent and surfactants are required. The products were characterized by powder X-ray diffraction, transmission electron microscopy and fourier transform infrared spectroscopy. The magnetic properties were evaluated using a superconducting quantum interference device. The elevating temperature procedures influence the sizes and the size distribution of the magnetite (Fe3O4) nanoparticles. A tentative mechanism of the formation of Fe3O4nanoparticles is proposed to explain the formation of the magnetite nanoparticles.
