Preparation and application of molecularly imprinted polymers based on chitosan

Chitosan has excellent bio-degradability and unique molecular structure. The molecularly imprinted polymers prepared based on chitosan usually have high affinity and selectivity and therefore wide applications. This paper summarized the function of chitosan and modified chitosan in the preparation of molecularly imprinted polymers,then reviewed latest development of molecularly imprinted polymers based on chitosan in environmental protection,medicine,separation and identification of protein,chiral compounds and adsorption for functional compounds. Advantages,disadvantages and development directions of these polymers in various fields were analyzed. Additionally,some application prospects of these molecularly imprinted polymers were discussed from the perspectives of green molecular imprinting technology and its combination with electrochemical sensor.
