利用缩醛基团连接的金纳米粒子修饰介孔二氧化硅，开发了一种新的pH响应性杂化纳米门系综。在酸性环境中缩醛连接基的水解使得金纳米颗粒作为看门人来控制客体分子在不同pH下从介孔二氧化硅中的释放。
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.
