Quadruple Stimuli‐Responsive Mechanized Silica Nanoparticles: A Promising Multifunctional Nanomaterial for Diverse Applications

Novel quadruple stimuli‐responsive mechanized silica nanoparticles were constructed by installation of supramolecular nanovalves onto the exterior surface of mesoporous silica nanoparticles. The release of cargo molecules is triggered by acid/Zn2+/alkali/reduction potential stimuli. This has potenti...

Description
Summary:Novel quadruple stimuli‐responsive mechanized silica nanoparticles were constructed by installation of supramolecular nanovalves onto the exterior surface of mesoporous silica nanoparticles. The release of cargo molecules is triggered by acid/Zn2+/alkali/reduction potential stimuli. This has potential application in the development of drug delivery systems or construction of smart anticorrosion coatings. Fourth time′s the charm: Mesoporous silica nanoparticles grafted with unique supramolecular nanovalves: The controlled release behaviors can be triggered by quadruple stimuli: acid/alkaline/Zn2+/reduction.
