Accelerated development procedure for molecularly imprinted polymers using membrane filterplates.
A novel technique for the synthesis and testing of large numbers of molecularly imprinted polymers is described requiring much less time than the commonly used miniMIP approach. Instead of vials, the polymers are synthesized on the surface of microfiltration membranes in multiwell filterplates. The thin polymeric films enable accelerated template removal. The MIP development procedure is thereby shortened to two days. Performance of the system was demonstrated by creating a combinatorial library of MIPs selective for cimetidine, an antiulcer drug. The polymer composition has been optimized. An experimental design combined with a multivariate analysis (i.e., response surface modeling) was used to minimize the number of experiments in the optimization process. The highest imprinting factor was obtained using a MAA/EDMA/template molar ratio of 3.5:19.5:1.
