查询词典 spheric segment

The stability of GA-PBCA-NP was also studied.ResultsDue to the agglomerationg of nanoparticles with no stabilizer,it was difficult to preparate.GA-PBCA-NP produced by the two methods both had spheric and smooth outer appearance,uniform distribution,nonadherence and stability.The diameter,ebeding ratio and drug loading in GA-PBCA-NP produced by emulsification polymerization and interfacial polymerization methods were 90～600 nm and 200 nm,60.49% and 73.87%,18.15% and 22.23%,respectively.

结果未添加稳定剂的纳米球表面粘连团聚现象严重，难以成球；乳化聚合法制备的GA-PBCA-NP在透射电镜下观察表面圆整光滑，粒子之间不团聚，不黏连，粒径范围在90～600 nm，包封率为60.49%，载药量为18.15%；界面缩聚法制得的纳米粒表面圆整光滑，粒子之间不团聚，不黏连，粒径大小均匀，都在200 nm左右，包封率为73.87%，载药量为22.23%，两种方法制备的稳定性都较好。
