Recent Progress on the Controlled Release of Stimuli-responsive Microcapsules

Owing to their unique properties such as high stability, versatility, tunable membrane properties, and capability of delivering a variety of core substances, stimuli-responsive microcapsules have been applied to a wide range of areas, including drug encapsulation and release, artificial cells, catalysis, and chemical sensors. This review focused on the development of various types of stimuli-responsive microcapsules, including thermo-responsive, pH-responsive, magnetic-responsive, biological-responsive, electro-responsive, and light-responsive microcapsules in the area of controlled release application, among which the release process of light-responsive microcapsules was especially emphasized. Finally, the future prospects of the controlled release of microcapsules were discussed.
