非酶纳米器件的促进化学激发光动力学灭杀肿瘤细胞研究
首发时间:2020-04-08
摘要:构建了一种非酶纳米反应器,研究其采用光动力学治疗法杀死癌细胞的效果。以正硅酸乙酯(TEOS)原料合成了中空介孔的纳米反应器(HMSNA@SCP),用扫描电镜(SEM)和透射电镜(TEM)对HMSNA@SCP的结构进行了表征,并用培养了48小时的HeLa细胞通过MTT法和流式细胞技术考察HMSNA@SCP对癌细胞的毒性作用,同时通过单线态氧探针(ABDA)检测HMSNA@SCP产生单线态氧的能力。实验结果显示:HMSNA@SCP粒径均匀,约为125 nm左右,具有较大的中空结构,同时能产生大量的单线态氧。细胞实验显示HMSNA@SCP能有效的杀死HeLa细胞。综上,HMSNA@SCP能有效的用于光动力学杀死癌细胞。

Nonenzymatic Nanodevice for Enhanced Chemo-Excited Photodynamic Killing of Cancer Cells
Abstract:A nonenzymatic nanoreactor was constructed to investigate the effect of photodynamic therapy on killing cancer cells.A hollow mesoporous nanoreactor (HMSNA @ SCP) was synthesized from ethyl orthosilicate(TEOS).The structure of HMSNA @ SCP was characterized by scanning electron microscope (SEM) and transmission electron microscope (TEM).HeLa cells cultured for 48 hours were used to investigate the toxic effect of HMSNA @ SCP on cancer cells by MTT method and flow cytometry.At the same time, the ability of HMSNA @ SCP to generate singlet oxygen was detected by singlet oxygen probe (ABDA).
Keywords: nanoreactor singlet oxygen photodynamic therapy Hollow mesoporous silicon
