The aim of this work was to investigate the possibility of employing semi-covalent molecularly imprinted polymers (MIPs) as a controlled release device for ibuprofen and naproxen in biological fluids, especially gastrointestinal ones, compared to non imprinted polymers (NIPs). The carboxyl groups of ibuprofen and naproxen were converted to vinyl ester group by reacting ibuprofen and vinyl aceta...

The aim of the present research work was the synthesis of molecularly imprinted polymers (MIPs) with a rod-like geometry via "mesophase polymerization". The ternary lyotropic system consisting of sodium dodecyl sulfate (SDS), water, and decanol was chosen to prepare a hexagonal mesophase to direct the morphology of the synthesized imprinted polymers using theophylline, methacrylic acid, and eth...

Background & Aims: Nowadays usage of molecularly imprinted polymers which act as artificial antibodies and separate target molecules from biological environments is a novel approach. Cholesterol is one of the major risk factors of cardiovascular diseases and its precise determination is crucial. In this research, a molecularly imprinted polymer by means of Fe3O4 nanoparticles coated with s...

Molecularly imprinted polymers are synthetic polymers possessing specific cavities designed for target molecules. They are prepared by copolymerization of a cross-linking agent with the complex formed from a template and monomers that have functional groups specifically interacting with the template through covalent or noncovalent bonds. Subsequent removal of the imprint template leaves specifi...

Molecularly imprinted polymers were prepared using a protein-conjugated disulfide cleavable monomer. After removing the protein by disulfide reduction, a thiol-reactive fluorophore was introduced into the thiol residue located only inside the imprinted cavity, resulting in specific transduction of the binding events into fluorescence spectral change.

Nowadays, it is still difficult for molecularly imprinted polymers (MIPs) to achieve homogeneous recognition since they cannot be easily dissolved in organic or aqueous phase. To address this issue, soluble molecularly imprinted nanorods have been synthesized by using soluble polyaniline doped with a functionalized organic protonic acid as the polymer matrix. By employing 1-naphthoic acid as a ...
