A novel near-infrared light responsive microcapsule system, gold nanorod-covered DOX-loaded hollow CaCO₃ microcapsule (AuNR-HM-DOX) is developed for cancer therapy. The hollow CaCO₃ microcapsules were prepared based on the self-assembly between chitosan and sodium alginate on CaCO₃ particles via layer-by-layer technique, and then covered with gold nanorods to obtain the microcapsule system. Upon near-infrared (NIR) irradiation, microcapsule with gold nanorods can convert the absorbed NIR light into heat. Meanwhile, doxorubicin (DOX), a chemotherapy drug, is loaded into the microcapsule system via electrostatic adsorption for combined photothermal therapy and chemotherapy. Properties of AuNR-HM-DOX including grain diameter, optical spectra were characterized. Confocal fluorescence imaging was performed to observe the morphology of the capsules and existence of DOX in the core, confirming the successful loading of DOX. The release of DOX from the capsules under continuous NIR irradiation was investigated to evaluate the temperature responsiveness of AuNR-HM-DOX. Results indicate that AuNR-HM-DOX microcapsules possess uniform particle size and high light responsiveness. The combination of chemical and physical therapy of AuNR-HM-DOX features great potential as an adjuvant therapeutic alternative material for combined cancer therapy.

对惯性约束聚变靶用聚合物微胶囊的制备方法进行了研究，设计了一种基于双T型结构的微通道乳化装置，用于制备稳定的双重乳液。使用玻璃毛细管作为中间相溶液的微通道，可以提高三相流速的调节范围，从而加大乳液尺寸分布范围。三相溶液密度差异小，因此乳液的同心度可以逐渐自发调整。通过调节不同的固化转速，发现在55 r/min下微球的同心度达到最佳，超过98.7%。使用扫描电镜对靶丸进行形貌和X射线能量色散谱分析表明，超临界干燥方法可以同时满足去除内部溶剂和保持靶丸结构不受破坏的要求。最终成功制得了粒径300～1000 μm、壁厚20～300 μm的聚丙烯腈空心微胶囊。

利用十八胺改性的酞菁绿G作为绿色显示颗粒, span80为电荷控制剂, 四氯乙烯为分散介质, 油溶黄为背景色, 制备稳定的电泳液, 采用界面聚合法制备出电子墨水微胶囊。研究了改性后的酞菁绿G 颗粒在电泳液中分散性和颗粒大小分布, 通过SEM照片证明, 当十八胺的质量分数为4%时, 酞青绿G在四氯乙烯下分散效果最好。对电泳液进行微胶囊化处理后, 在E=50 V/mm电场下, 微胶囊中的颗粒可以进行可逆运动。
