Intelligent Hydrogels exhibit reversible swelling behavior in response to external stimulation,such as temperature,pH,solvent,ionic strength,electric field,magnetic field,light,pressure,specific analyte,etc.Improving the characteristic of intelligent hydrogels by molecular imprinting technique,those hydrogels not only have the ability of environmental responsiveness,but also have the specialty of molecular recognition.Hence,the molecularly imprinted intelligent hydrogels can auto-recognize and bind/release the specific analyte in respons to the external stimuli,which has potential application in delivery of drug,biosensors and immune analyse.In this paper,the development of molecularly imprinted intelligent hydrogels is reviewed.The challenges and the research tendency are discussed.
