A versatile approach for the preparation of photoswitchable molecularly imprinted polymers (MIPs) is proposed where the selective recognition and the photoresponsive function are assumed by two different monomers. As a proof of concept, MIP microspheres were synthesized by precipitation polymerization for recognizing terbutylazine, a triazine-type herbicide. Formation of the selective binding s...

During the last decades molecularly imprinted polymers (MIPs) have attracted significant attention as a novel stationary phase for chromatographic applications, which can overcome limitations of commonly used materials, first of all, poor selectivity of the retention mechanism. Recently, polymeric membranes instead of columns filled with polymer particles have achieved commercial importance in ...

In this study, electrochemical molecularly imprinted sensors were fabricated and used for the determination of ascorbic acid (AA). Nanofiber membranes of cellulose acetate (CA)/multi-walled carbon nanotubes (MWCNTs)/polyvinylpyrrolidone (PVP) (CA/MWCNTs/PVP) were prepared by electrospinning technique. After being transferred to a glass carbon electrode (GC), the nanofiber interface was further ...

We report the synthesis of small (below 100 nm), stable and water-compatible superparamagnetic molecularly imprinted nanocomposites using water-soluble, dithiocarbamate-based photoiniferters. These agents were adsorbed directly on surface maghemite nanoparticles allowed thin layers polymer able to specifically selectively bind green fluorescent protein as a model protein. To best or our knowled...

A new selective and sensitive sensor based on molecularly imprinted polymer/acetylene black (MIP/AB) was developed for the determination of azithromycin (AZM) in pharmaceuticals and biological samples. The MIP of AZM was synthesized by precipitation polymerization. MIP and AB were then respectively introduced as selective and sensitive elements for the preparation of MIP/AB-modified carbon past...

Food Sci., 32: 449–455. A new and hydrophilic molecularly imprinted polymer (MIP) selective for olaquindox was prepared by bulk polymerisation using methacrylic acid as the functional monomer and ethy...
