Uniform magnetic nanoparticles were prepared by chemical coprecipitation. Decanoic acid was used as the first surfactant to minimize the magnetic dipole-dipole interaction, and starch, citric acid, decanoic acid, polyethylene glycol and alginic acid were selected as the second surfactants for hydrophilicity. The applied second surfactants strongly influenced the biological toxicity of the magnetic particles as well as the properties of magnetic fluids. (C) 2006 Elsevier B. V. All rights reserved.
