以无定形聚对苯二甲酸乙二酯/间苯二甲酰胺为原料制备了分子印迹聚合物膜。Z-D-Glu印迹膜识别与印迹分子绝对构型相同的D-异构体，而不识别相应的L-异构体，反之亦然。膜优先吸附的氨基酸也可通过电渗析选择性渗透。当外加电势差为2.0V时，分离因子达到2.0。
Molecularly imprinted polymeric membranes were prepared from amorphous poly(hexamethylene terephthalamide/isophthalamide). Membranes imprinted by Z-D-Glu recognize the D-isomer, of which absolute configuration is the same as that of the print molecule, in preference to the corresponding L-isomer, and vice versa. The amino acid preferentially adsorbed by the membrane was also selectively permeated by electrodialysis. An optimum separation factor of 2.0 was reached at the applied potential difference of 2.0 V.
