Molecularly imprinted polymer using beta-cyclodextrin as functional monomer for the efficient recognition of bilirubin

Anal Chim Acta. 2008 Jan 7;606(1):92-7. doi: 10.1016/j.aca.2007.10.044. Epub 2007 Nov 4.

Abstract

Bilirubin (BR) imprinted polymer was successfully prepared using supramolecular host compound beta-cyclodextrin (beta-CD) as functional monomer. The adsorption equilibrium was attained in about 4 h, which indicated that the adsorption kinetics was comparatively fast. The results of adsorption and selectivity experiments indicated that BR-imprinted beta-CD polymer was able to bind BR specifically and reversibly. The specific recognition of BR-imprinted beta-CD polymer for BR may be due to the cooperative effects of inclusion interaction and hydrogen bonding. This BR-imprinted beta-CD polymer was further applied to eliminate BR in human serum sample. It was verified that the binding specificity of the BR-imprinted polymer for BR was essentially sufficient in the presence of other compounds coexisting in serum sample. Therefore, as a reusable material possessing high affinity and selectivity, BR-imprinted beta-CD polymer has a potential application perspective as a clinical hemoperfusion material.
