本文介绍了聚合物胶束的材料选择依据，以及制备技术，并提出了一种新的胶束设计策略——双药载药胶束。

Here we introduce the strategy of choosing polymers and the technology of preparing micelles. Moreover, we bring up a new design strategy of polymeric micelles, named as binary-drug loaded micelles.

通过透射电镜观察、动态光散射测定、紫外吸光度测定等手段分析胶束的微观形态、粒径大小和载药量、测定了载药胶束的体外释药速率。

Microscopic morphology, diameter and drug-loaded amount of the micelles were examined by means of TEM, DLS and UV respectively, and their in vitro drug release rates were measured.
