This is the first direct experimental probe, using EXAFS, of the active site within molecularly imprinted polymers and paves the way to a more detailed understanding of the inner workings of molecular imprinting.

In this research, selective adsorption of U(VI) in aqueous solutionsin the presence of various lanthanide ions by using U(VI)-imprinted cryogel polymer was conducted. For this purpose, the prepared pHEMA-(MAH)3-U(VI) cryogel polymer by free radical polymerization method. U(VI) was desorbed with 5.0 mol/L HNO3 and thus U(VI)-imprinted were created onto p-HEMA-(...

Solid phase extraction is one of the major applications of molecularly imprinted polymers fields for clean-up of environmental and biological samples namely molecularly imprinted solid-phase extraction. In this study, solid phase extraction using the imprinted polymer has been optimized with the experimental design approach for a triazine herbicide, named atrazine with regard to the critical fa...

New fluorescent ion-imprinted polymers (IIPs) specific for Pb(II) detection were synthesized by precipitation polymerization. The activity of the IIPs was provided a functional monomer, ANQ-ST, based on chelating 5-amino-8-hydroxyquinoline moiety coupled to anthracene and styrenic group. Various synthesis parameters tested: metal/functional monomer ratio, polymerization solvent crosslinker (eth...

Molecular imprinting is a well-established technology to mimic antibody-antigen interaction in a synthetic platform. Molecularly imprinted polymers and nanomaterials usually possess outstanding recognition capabilities. Imprinted nanostructured materials are characterized by their small sizes, large reactive surface area and, most importantly, with rapid and specific analysis of analytes due to...

A novel ion-imprinted polymer, lead ion-imprinted micro-beads with combination of two functional monomers, was synthesized using the W/O/W polymerization method. Two functional monomers, 1,12-dodecanediol-O,O'-diphenyl-phosphonic acid (DDDPA) and 4-vinylpyridine, were used to form a suitable construction with micro-pores fitting the template and recognition sites. The effects of adsorbent dosag...

A new ruthenium ion imprinted polymer was prepared from the Ru(III) 2-thiobarbituric acid complex (the template), methacrylic acid or acrylamide (the functional monomers), and ethylene glycol dimethacrylate (the cross-linking agent) using 2,2'-azobisisobutyronitrile as the radical initiator. The ion imprinted polymer was characterized and used as a selective sorbent for the solid phase extracti...
