| Abstract: | Carboxylate modified magnetic microspheres were prepared by using modified suspension polymerization method. Their structure, size distribution and magnetic content were measured. The effect of monomer water ratio, methyl acrylate monomer ratio, temperature and time of reactions were studied. Their biological absorptions of b γ IgG to the magnetic microsphere were characterized by means of radiation immunology method. The optimum conditions of preparation for the magnetic microspheres with good biological absorption were studied. |
