Molecularly Imprinted

Molecularly imprinted polymer microspheres for selective binding and recognition of atenolol were prepared by means of precipitation polymerization method using methacylic acid as functional monomer and trimethylolpropane trimethacrylate as cross-linker in the presence of atenolol as template molecule in acetonitrile solution. Computer simulation was employed to demonstrate the mechanism of the interaction between methacylic acid and atenolol. The scanning electron microscopy exhibited that the polymers were uniform spheres with the diameter of about 0.6µm. The adsorption properties of atenolol for imprinted microspheres were evaluated by equilibrium rebinding experiments. Scatchard plot analysis revealed that there were two classes of binding sites in the imprinted microspheres. The dissociation constant and the apparent maximum binding capacity were 4.56×10-4mol/L and 186.46μmol/g for the high affinity binding sites, 2.40×10-2mol/L and 4.01mmol/g for the low affinity binding sites. Compared to the structrally analogues, the imprinted microspheres exhibited a high selective reconizable capacity towards the template.

Molecular imprinting technology has become an interesting research area to the preparation of specific sorbent material for environmental and occupational sample preparation techniques (1). In the molecular imprinting technology, specific binding sites have been formed in polymeric matrix, which often have an affinity and selectivity similar to antibody-antigen systems (2). In molecular imprinted technology, functional monomers are arranged in a complementary configuration around a template molecule, then, cross-linker and solvent are also added and the mixture is treated to give a porous material containing nono-sized binding sites. After extraction of the template molecule by washing, vacant imprinted sites will be left in polymer, which are available for rebinding of the template or its structural analogue (3). The stability, convention of preparation and low cost of these materials make them particularly attractive (4). These synthetic materials have been used for capillary electrochromatography (5), chromatography columns (6), sensors (7), and catalyze system (8). Depending on the molecular imprinting approach, different experimental variables such as the type and amounts of functional monomers, porogenic solvent, initiator, monomer to cross-linker ratio, temperature, and etc may alter the properties of the final polymeric materials. In this work, chemometric approach based on Central Composite Design (CCD) was used to design the experiments as well as to find the optimum conditions for preparing appropriate diazinon molecularly imprinted polymer.

Polymerization Method

Polystyrene microspheres were prepared by the emulsifier-free polymerization method. Using the polystyrene microspheres as seeds, 2,4-dichlorophenoxyacetic acid as template molecules, the monodispersed molecularly imprinted polymer microspheres (MIPMs) were prepared by a single-step swelling and polymerization method. The monodispersed molecular imprinted polymers with porous structure were characterized by SEM, and UV-visible spectrophotometry. The adsorption performance of MIPMs for 2,4-dichlorophenoxyacetic acid was investigated.
