Molecular imprinting is a new and rapidly evolving technique used to create synthetic receptors and it possesses great potential in a number of applications in the life sciences. Keeping in mind the therapeutic importance of 5-fluorouracil (5-FU) and the technological significance of molecular imprinting polymers, the present study is an attempt to synthesize 2-hydroxyethylmetacrylate- and acry...
The copolymer metal complexes in the form of imprinted polymers were prepared from Poly (vinyl alcohol) (PVA), Acrylic acid (AAc), Acrylamide (AAm) and 2-Acrylamido-2methyl propane sulfonic acid (AMPS) monomers irradiated in presence of different metal ions and crosslinking agent. Characteristics and some properties of the prepared imprinted and grafted polymers were investigated. Also the poss...
Molecular imprinted Polymers (MIP) targeted for Tobacco mosaic virus (TMV) have been synthesized. Batch equilibrium studies using imprinted and non-imprinted polymer hydrogels in TMV and TNV solutions were conducted to determine virus-binding capacities. TMV-imprinted hydrogels showed increased binding to TMV (8.8 mg TMV/gpolymer) compared to non-imprinted hydrogels (4.2 mg TMV/gpolymer). Furth...
Chitosan is widely used in molecular imprinting technology (MIT) as a functional monomer or supporting matrix because of its low cost and high contents of amino and hydroxyl functional groups. The various excellent properties of chitosan, which include nontoxicity, biodegradability, biocompatibility, and attractive physical and mechanical performances, make chitosan a promising alternative to c...
The application of molecularly imprinted polymers (MIPs) as molecular scavengers for ambient plasma ionization mass spectrometry has been reported for the first time. MIPs were synthesized using methacrylic acid as functional monomer; nicotine, propyphenazone, or methylparaben as templates; ethylene glycol dimethacrylate as a cross-linker; and 2,2'-azobisisobutyronitrile as polymerization initi...
In this research a new type of magnetic Pb(II) and Cr(VI) ion-imprinted polymers were synthesized using Fe3O4@SiO2 magnetic particles as supporter, benzoyl phenyl hydroxylamine and dithizone as ligands for Pb and Cr ions respectively, 4-vinyl pyridine as functional monomer, ethylene glycol dimethacrylate as crosslinker and 2,2′-azobis(isobutyronitrile) as the initiator. The ionic templates were...
Dual-template magnetic molecularly imprinted polymer nanoparticles were synthesized and used for the solid-phase extraction of acetaminophen and codeine before simultaneous determination by corona discharge ion mobility spectrometry. The magnetic molecularly imprinted polymer nanoparticles were prepared using silica-coated magnetic nanoparticles as supporters, acetaminophen and codeine as templ...
A sensitive electrochemical molecularly-imprinted sensor was developed for the detection of aflatoxin B1 (AFB1), by electropolymerization of p-aminothiophenol-functionalized gold nanoparticles in the presence of AFB1 as a template molecule. The extraction of the template leads to the formation of cavities that are able to specifically recognize and bind AFB1 through π-π interactions between AFB...
Many research studies have been conducted on the use of conjugated polymers in the construction of chemical sensors including potentiometric, conductometric and amperometric sensors or biosensors over the last decade. The induction of conductivity on conjugated polymers by treating them with suitable oxidizing agents won Heeger, MacDiarmid and Shirakawa the 2000 Nobel Prize in Chemistry. Common...
