Abstract:
Environmental stimuliresponsive smart microcarrier materials, which can realize selfregulated controlled release in response to the change of temperature, pH, magnetic field and special chemicals in external environment, exhibit excellent superiorities in various fields, such as drug delivery, immobilization of enzyme and cells, and separation and purification of chemicals. The progress in development of environmental stimuli responsive smart microcarrier materials are reviewed, in which the smart gating microcapsules for controlled release and smart microcapsules for controlled burstrelease are introduced. Especially, the thermoresponsive, glucoseresponsive and ion recognition smart gating microcapsules for controlledrelease as well as the thermoresponsive, pH responsive and ionrecognition smart microcapsules for burst release are introduced and reviewed systematically. At present, environmental stimuli responsive smart microcarrier materials are still in the basic research stage and need intensive study and further development.
