Hollow mesoporous silica nanoparticles (HMSs) were modified by β-cyclodextrin via a âclickâ reaction, an amphiphilic copolymer with a trans-azobenzene structure was then assembled onto β-cyclodextrin to cover the surface of the HMSs. The prepared nanocomposites can release drugs in a ârelease-stop-releaseâ manner by converting light irradiation.
通过“点击”反应,将β-
环糊精修饰到空心中孔
二氧化硅纳米颗粒(
HMSs)上,随后在β-
环糊精上组装具有反式
偶氮苯结构的 amphiphilic copolymer(双亲共聚物),以覆盖
HMSs的表面。制备得到的纳米复合材料可以通过光照射转换以实现“释放-停止-释放”的药物释放模式。
