＜正＞Molecular imprinting is a technique for preparing chemically selective binding sites,which recognize a particular molecule,in a macroporous polymer *** producing of molecularly imprinted polymers（MIPs） involves polymerization in solution of a target molecule（template）with functional and crosslinking monomers. Removal of the template molecule from a resultant polymer leaves behind specific recognition sites that are complementary to the template and enable the polymer to selectively rebind the imprint molecule from a mixture of closely related *** M1Ps can be produced in a covalent or non-covalent *** the case of covalent approach of molecular imprinting covalent bonds between the template and polymerizable monomers are *** order to remove the template from the polymer to liberate the binding sites,these covalent bonds have to be chemically ***-covalent approaches are based on the formation of a prepolymerization complex between monomers and the template trough noncovalent bonds such as ionic interactions or hydrogen *** enables the removal of the template simply by solvent extraction. Because MIPs have outstanding advantages such as predetermined selectivity,simple and convenient preparation,robustness in organic solvents and acidic or basic reagents,and durability to high temperature, molecular imprinting has drawn extensive attention.
