以玉米淀粉为原料，环氧氯丙烷为交联剂，采用逆相悬浮交联聚合法合成了淀粉微球。电镜扫描显示，微球为圆形，表面粗糙，以酮洛芬为模型药物，微球吸附载药量为140mg／g。
Using starch as raw material and epichlorohydrin as crosslinking agent, starch microspheres were synthesized by reverse phase suspension polymerization. Electron microscopy showed that the microspheres were round and the surface was rough. Ketoprofen was used as a model drug and the microspheres loaded with drug loading was 140 mg / g.
