[Study of magnetic microspheres for purging cancer cells from bone marrow. II. Preparation of polystyrene magnetic microspheres. ].
Magnetic microspheres (MS) used to purge tumor cells from human bone marrow were prepared with a two step method. Main factors that can influence the magnetization result were discussed. The MS were coated with polyacrolein which has active aldehyde group. The magnetic material content and the magnetic response of MS were determined and showed that the magnetic material y-Fe(2)O(3) by X-ray diffraction.
