Molecular recognition plays an important role in biological and chemical processes. Since molecular imprinting techniques can afford complementary binding sites for a target molecule, the molecularly imprinted polymer (MIP) for the target molecule has been used for its specific recognition as chromatographic media, solid-phase extraction media, artificial antibodies, membranes and sensors[1-4]. Usually, MIPs were prepared by a bulk polymerization method. However, the disadvantage of the method is that the obtained block polymers should be crushed, ground and sieved to produce high performance liquid chromatographic (HPLC) packing materials. Recently, we prepared the uniformly sized MIPs by a multi-step swelling and polymerization method[5], which is suitable for preparing HPLC packing materials, and renders in situ modification susceptible.
