Abstract: Molecular imprinting separation technique can effectively separate the target molecules from impurities by specially binding the target molecules based on imitating the way of interaction between antigen and antibody. It is a very promising separation technique. In the traditional molecular imprinting techniques, imprinted polymers are usually prepared for selectively adsorbing the template molecule in organic solvents. However, most of the practical applications of molecular imprinting technique are in aqueous media. Thus, molecular imprinting separation technique in aqueous media receives more and more attention by scientific researchers in recent years. This review covers the recent progress of molecular imprinting separation technique from the following directions: design principle and synthesis methods of imprinted polymers in aqueous media; separation mechanism of water-compatible molecularly imprinted polymers; applications of water-compatible molecular imprinting separation technique in analytical chemistry. Moreover, the existing problems and the outlook of this technique are discussed.
