ABSTRACTMolecularly imprinted micro- and nano-particles can be conveniently prepared using precipitation polymerization method. By controlling the initial reaction composition, the resulting polymer particles may be obtained as uniform beads that display favourable binding characteristics. Incorporation of a novel reporter element resulted in an imprinted scintillation polymer that displayed an enhanced signalling efficiency.

Uniformly-sized, molecularly imprinted polymers (MIPs) for (D)-naproxen have been prepared by a precipitation polymerization method using methacrylic acid (MAA) as a functional monomer and divinylbenzene (DVB) as a cross-linker in acetonitrile or a mixture of toluene and acetonitrile(1:3). The (D)-naproxen-imprinted MAA-co-DVB polymers were monodispersed microspheres with size in the range of 1.5 to 3.6µm. Enantioseparation of naproxen was attained using the (D)-naproxen-imprinted MAA-co-DVB polymer microspheres. When Ethylene glycol dimethacrylate(EGDMA) was used as a cross-linker, the MAA-co -EGDMA polymers were sub-microspheres with the average size of 350nm and showed very low affinity for the template (D)-naproxen . The (D)-naproxen-imprinted MAA-co-DVB polymer microspheres prepared in the mixture of toluene showed the highest molecular recognition ability and with the biggest size of 3.6µm.

The synthesis of molecularly imprinted polymers (MIPs) was carried out by using methacrylic acid as a monomer, ethylene glycol dimethacrylate as a crosslink and dibutyl phthalate as a mold through the precipitation polymerization method. The MIP was characterized with FTIR, surface area analyzer, SEM-EDS and ultraviolet-visible spectrophotometer. The MIP adsorption ability test variables for dibutyl phthalate were time and concentration. The FTIR indicates that the functional groups –OH, –C=O and –C=C contribute to the formation of MIP and the SEM-EDS analysis showed that the prepared MIP resembles as beads. The MIP’s ability to adsorb dibutyl phthalate is better than NIP and the optimum time to adsorb dibutyl phthalate is 60 min.
