A survey of commercially available amine-based monomers for binding and selectivity of carboxylate and phosphonic acid templates has revealed that the best selectivity is found for the pyridine-based monomers, while the highest affinity was found for 2-(dimethylamino)ethyl methacrylate (2-DEMA, 1). In fact, a more general finding is that selectivity is higher for aromatic amine-based monomers even though affinity remains higher for aliphatic amine-based monomers. An attempt to combine the optimal properties of these two classes of amine monomers, i.e. 2-vinylpyridine (2-VPY, 2), and 2-DEMA by using both simultaneously in a single imprinted polymer resulted in an MIP whose properties were dominated by the aliphatic amine-based monomer 2-DEMA. A controversy between the two commercially available vinylpyridine monomers, 2-VPY and 4-vinylpyridine (4-VPY, 3), was investigated, revealing that neither monomer is generally better for molecular imprinting; rather, the choice of 2-VPY or 4-VPY is template specific (although the preponderance of data tends to frequently favor 4-VPY). Phosphonic acid templates proved to be less successful as templates for molecular imprinting versus carboxylate functionalized templates, although binding was obtained and shown to be controllable via an ion-exchange process.

Molecularly imprinted polymers are synthetic antibody mimics formed by the crosslinking of organic or inorganic polymers in the presence of an analyte which yields recognitive polymer networks with specific binding pockets for that biomolecule. Surface imprinted polymers were synthesized via a novel technique for the specific recognition of bovine serum albumin (BSA). Thin films of recognitive networks based on 2-(dimethylamino)ethyl methacrylate (DMAEMA) as the functional monomer and varying amounts of either N,N'-methylenebisacrylamide (MBA) or poly(ethylene glycol) (400) dimethacrylate (PEG400DMA) as the crosslinking agent were synthesized via UV free-radical polymerization and characterized. A clear and reproducible increase in recognition of the template BSA was demonstrated for these systems at 1.6-2.5 times more BSA recognized by the MIP sample relative to the control polymers. Additionally, these polymers exhibited selective recognition of the template relative to competing proteins with up to 2.9 times more BSA adsorbed than either glucose oxidase or bovine hemoglobin. These synthetic antibody mimics hold significant promise as the next generation of robust recognition elements in a wide range of bioassay and biosensor applications.
