Y1 - 2009/// T1 - Synthesis and Magnetic Properties of Fe(3)O(4) Nanoparticles Coated with Biocompatible Double Hydrophilic Block Copolymer JF - Journal of Nanoscience and Nanotechnology VL - 9 IS - 8 SN - 1533-4880 U3 - 10.1166/jnn.2009.1275 PB - American Scientific Publishers SP - 4753–4759EP - UR - https://hdl.handle.net/10442/12668 N2 - Fe(3)O(4) nanoparticles coated with double hydrophilic biocompatible poly(sodium(2-sulfamate-3-carboxyl ate) isoprene)-b-poly (ethylene oxide) block copolymer were prepared by a one step precipitation method. The magnetic nanoparticles have 15 nm mean diameter (TEM), 68 nm hydrodynamic diameter, -30.10 mV zeta-potential and form very stable dispersion in aqueous media. Structural characterization using powder XRD and Mossbauer spectroscopy establish the magnetite phase, while thermogravimetric analysis and FT-IR spectroscopy confirm the presence of the block copolymer on the nanoparticles surface. The magnetic properties were determined using a vibrating sample magnetometer (VSM) at room temperature and reveal superparamagnetic behavior while the composite materials shows high saturation magnetization up to 67.7 emu/gr.
