摘要:【中文】本发明属于生物医用材料技术领域,具体涉及一种光热敏感型羧甲基壳聚糖纳米载药微球,该纳米载药微球以聚合物羧甲基壳聚糖/N‑异丙基丙烯酰胺为骨架,负载腙键结合的纳米金‑盐酸阿霉素于所述骨架表面形成的纳米微球。本发明还提供了上述纳米载药微球的制备方法。本发明所提供的光热敏感型羧甲基壳聚糖纳米载药微球,不仅解决了壳聚糖难溶于水的问题,同时通过改变近红外光照和温度的条件,使纳米微球材料发生相变,亲水链崩塌,溶剂化层被破坏,缓慢释放药物,提高药物的载药率,把控药物精准释放。 【EN】The invention belongs to the technical field of biomedical materials, and particularly relates to a photothermal sensitive carboxymethyl chitosan nano drug-loaded microsphere, which is formed by taking polymer carboxymethyl chitosan/N-isopropyl acrylamide as a framework and loading nanogold-doxorubicin hydrochloride combined with hydrazone bonds on the surface of the framework. The invention also provides a preparation method of the nano drug-loaded microsphere. The photo-thermal sensitive carboxymethyl chitosan nano drug-loaded microsphere provided by the invention not only solves the problem that chitosan is difficult to dissolve in water, but also enables the nano microsphere material to generate phase change, hydrophilic chain collapse and solvolysis layer to be damaged by changing the conditions of near-infrared illumination and temperature, so that the drug is slowly released, the drug loading rate of the drug is improved, and the controlled drug is accurately released.
