A simple and effective process has been proposed to prepare chitosan/magnetite nanocomposite beads with saturation magnetization value as high as uncoated Fe3O4 nanoparticles (ca. 54emu/g). The reason was that the coating chitosan layer was so thin that it did not affect magnetic properties of these
