Abstract
Recently, magnetism fluid is attracted attention since it has fine particle and magnetic property from engineering and medical field. In this study, there are purposes that the application of magnetism fluid as bio-material. Therefore, samples created by this study need the biocompatibility and dispersion stability. And samples are formed as magnetic fine particle is coated by saccharide (i.e. magnetite is selected as the core material and monosaccharide is selected as covered material). If medication in the living body is taken into consideration, problem is control of particle diameter. So, synthesises were performed by lower molecular weight of saccharides. Synthetic method is coprecipitation, particle diameter is measured by DLS.
