摘要
Magnetic polymer microspheres can be bonded covalently to antibodies and to otherbiospecific molecules, for instance, cells, enzymes, toxins, hormones, growth factors, nucleicacids, drugs and radioisotopes, for use in a wide range of biomedical research studies andclinical procedures. Magnetic nanoparticles of iron oxide coated with dextran can be at-tached to bioactive substances by their pendant functional groups, and are small enough
