摘要
目的制备氧化介孔碳球纳米粒(oMCN),考察其理化性质以及作为抗肿瘤药物紫杉醇递送载体的研究。方法采用低浓度水热法合成介孔碳球纳米粒,观察其形貌特征,测定其介孔性质参数、粒径、Zeta电位、载药量大小,利用透析法研究体外释药行为,用CCK-8法考察体外抗肿瘤活性。结果 oMCN的比表面积为704.63m2/g、孔容积为0.57cm3/g、孔径分布约为3.23nm、平均粒径为140nm、Zeta电位为-36mV、载药量高达45.6%,72h体外累积释药量为57.6%,具有良好的药物负载与缓释性能,对小鼠肺癌LLC细胞具有显著的抑制作用。结论 oMCN作为抗肿瘤药物紫杉醇的载体具有较好的应用前景。
