The effects of dipping time and precursor concentration on the membrane preparation and the separation performance showed that both PBZ membranes were remarkably stable, resistant to swelling, and provided an impressively high separation factor of higher than 10,000 for all ethanol concentration ranges, characteristics implying that they could be a good candidate for high purity ethanol production.

While the IgG-imprinted brush layers chip had almost the same affinity constant for target IgG as the nonimprinted brush layer chip, the affinity constant of the IgG-imprinted gel layer chip was approximately twice than that of the nonimprinted gel layer chip. These indicate that chemical crosslinks are very important factor to create distinct molecular recognition sites by molecular imprinting. Thus, biomolecular imprinting that uses biomolecular ligands and crosslinkers enables us to design polymer layer chips with distinct molecular recognition sites with a strong affinity for a target biomolecule. The molecularly imprinted gel layers chips with lectin and antibo...
