Colloids Surf B Biointerfaces:GO@Au纳米棒用于化学-光热治疗和阿霉素的释放

氧化石墨烯(GO)是石墨烯的一种衍生物,由于其固有的生物相容性,良好的载药能力以及抗菌,抗真菌等特性,已经成为了许多药物递送的关键载体。我们使用了一种称为阿拉伯胶(GA)的新型植物材料,以提高GO的溶解度,并在溶液中化学还原它。GA功能化的GO(fGO)在光热疗法治疗癌症中具有在近红外区域(NIR)吸收增加的现象。为了解可能影响其流变性质的GO的形状和尺寸效应,我们通过种子介导的方法原位合成GO@

氧化石墨烯(GO)是石墨烯的一种衍生物,由于其固有的生物相容性,良好的载药能力以及抗菌,抗真菌等特性,已经成为了许多药物递送的关键载体。

我们使用了一种称为阿拉伯胶(GA)的新型植物材料,以提高GO的溶解度,并在溶液中化学还原它。GA功能化的GO(fGO)在光热疗法治疗癌症中具有在近红外区域(NIR)吸收增加的现象。为了解可能影响其流变性质的GO的形状和尺寸效应,我们通过种子介导的方法原位合成GO@GNRs并将它们与金纳米棒(GNR)缀合。对于上述缀合物,在环境温度(28±2℃)下连接多柔比星(DOX)。还通过体外光热杀伤A549细胞系仔细研究了DOX与NIR暴露效应的释放动力学。

结果发现,NIR诱导的药物释放和光热性质的增强,这表明fGO@GNRs-DOX方法同时是化学疗法和光热疗法的理想选择。
