一种替代的分子印迹技术被用来获得用于对映选择性分离的聚合物膜。在该技术中，在从聚合物溶液浇铸聚合物膜的同时，将打印分子的“分子记忆”引入膜中。我们已经发现，含有来自L-氨基酸的寡肽残基并被L-氨基酸衍生物印迹的膜优先识别L-异构体而不是相应的D-异构体，反之亦然。通过电渗析的应用，优先吸附在膜中的氨基酸异构体可以跨膜运输。
An alternative molecular imprinting technique is used to obtain polymeric membranes for enantioselective separations. In this technique, the "molecular memory" of the print molecule is introduced into the membrane at the same time that the polymeric membrane is being cast from its polymer solution. We have found that a membrane which contains an oligopeptide residue from an L-amino acid and is imprinted by a L-amino acid derivative recognizes the L-isomer in preference to the corresponding D-isomer, andvice versa. By application of electrodialysis, the amino acid isomer which is preferentially adsorbed in the membrane may be transported across the membrane.
