Abstract:Environmental stimuli-responsive smart microcarrier materials,which can realize self-regulated 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 burst-release are introduced.Especially,the thermo-responsive,glucose-responsive and ion-recognition smart gating microcapsules for controlled-release as well as the thermo-responsive,pH-responsive and ion-recognition 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.
Keywords:microcarriers  environmental stimuli-response  controlled-release  smart microcapsules  functional materials
