Abstract
A new pH-responsive hybrid nanogated ensemble has been developed by using acetal group linked gold nanoparticle capped mesoporous silica. The hydrolysis of acetal linker at acidic environment makes the gold nanoparticles work as a gatekeeper to control the release of guest molecules from mesoporous silica under different pH's.
摘要
一种新的 pH 响应型杂化纳米门控组装体已通过使用连接缩醛基团的金纳米粒子封端的介孔硅来制备。在酸性环境下缩醛连接物的水解使得金纳米粒子作为一种门控开关来控制客体分子在不同 pH 值下从介孔硅中的释放。
