Molecularly imprinted technology(MIT) is also called molecular cyclostyle technology,which has become a strongly method in molecular recognising and trace analyzing.Using MIT to synthesize molecular imprinting polymers(MIPs) are synthesized.MIPs have extensive application.They have brought great attention in recent decades.MIPs are synthesized by employing molecularly imprinted technology(MIT),which are new functional polymers,with specific spacial recognition ability to some molecules.The methods and mechanisms of MIPs are introduced and its application progress in many fields are summarized.Because of its spacial recognition ability to some molecules,they are used in biosensors.Because of its ability of counteracting execrable environment,they are used in enzyme catalyzing.Because of ability of linking with compound that having similar construction to MIPs,they are employed in film separating and solid phase extraction.They are slso used in chemical catalyzing.
