We described a simple one-step process for the synthesis of oleic acid-capped magnetite nanoparticles using the dimethyl sulfoxide (DMSO) to oxidize the precursor Fe(2+) at 140 degrees C. By adjusting the alkalinity of the reaction system, magnetite nanoparticles with two sizes of 4 and 7 mn could be easily achieved. And the magnetite nanoparticles coated by oleate were well-monodispersed in organic solvent. (C) 2009 Yu Zhang. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
