合成了含有铁粉和抗癌药的明胶微球，这种微球在体外磁场的作用下具有定位作用。微球的粒径在０２～１３ｍｍ之间，粒径大小是由制备条件决定的。微球可用戊二醛进行固化。研究了微球体外药物的释放规律
Gelatin microspheres containing iron powder and anti-cancer drugs were synthesized, and the microspheres have the localization effect under the action of the magnetic field in vitro. The particle size of microspheres is between 02 ~ 13mm. The particle size is determined by the preparation conditions. Microspheres can be cured with glutaraldehyde. The release of drugs in vitro microspheres was studied
