    • The technique of molecular imprinting was invented by Wulff and Mosbach in the 1970s [6-9]. Its purpose was to create resins that selectively adsorbed some target molecules. Plastics consisting mostly of cross-linkers were copolymerized with target adsorbing monomers in the presence of the target molecules. The fundamental difference between our system and that of the conventional imprinting is in the ability to fold and unfold, which is a characteristic feature in the memory of conformation by polymers.

    • Watanabe and colleagues reported a study on the adsorption of norephedrine by NIPA/methacrylic acid copolymer gels. The gels were synthesized in a dilute monomer concentration and in both the presence and the absence of norephedrine. The former gel was found to adsorb more norephedrine than the latter in both collapsed and highly swollen states. From the observation that the former gel was opaque whereas the latter was clear, the authors concluded that the difference was due to microphase separation induced by the target. Since the molar concentration of the adsorbing monomers, methacrylic acid, (100 mM) was much higher than the cross-linking density (7 mM), the cross-links should not have created frustration. Thus the imprinting effect was in the macroscopic level and was not related to the memory of molecular conformation. See M. Watanabe, T. Akahoshi, Y. Tabata, and D. Nakayama, J. Am. Chem. Soc. 120, 5577 (1998).
