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...

Many researchers have studied the biosorption of different pollutants. However, a quite limited number of works focus on selectivity, which may be characterized as specific property for each biosorbent. Two main criteria need to be adopted for the selection and synthesis of modern biosorbents, such as their rebinding capacity and selectivity for only one target, molecule, ion, etc. Selective bi...

At this study, thallium (I) ion-imprinted polymer, as a novel sorbent for Tl (I) and comparison with Tl(III) ion-imprinted polymer has been synthesized. This sorbent for preconcentration and solid-phase extraction of Tl(I) ions from aqueous solutions, used. Through preparing the binary complex of Tl(I) ions with 5, 7-dichloroquinoline-8-ol (DCQ) the particles of thallium (I) Ion-Imprinted P...

The present review describes recent advances in the concept of molecular imprinting using metal organic frameworks (MOF) for development of chemical sensors. Two main strategies regarding the fabrication, performance and applications of recent sensors based on molecularly imprinted polymers associated with MOF are presented: molecularly imprinted MOF films and molecularly imprinted core-shell n...

The siderophore-based extraction of iron from the soil by bacteria is proposed as a model for a new separation methodology labeled the soil poultice, a molecular device that would selectively retrieve the complex of a targeted metal ion. In this first feasibility study we describe the synthesis and characterization of molecularly imprinted polymers based on noncovalent interactions, and their a...

This work has focused on the rational development of polymers capable of acting as traps of bile salts. Computational modeling was combined with molecular imprinting technology to obtain networks with high affinity for cholate salts in aqueous medium. The screening of a virtual library of 18 monomers, which are commonly used for imprinted networks, identified N-(3-aminopropyl)-methacrylate hydr...

Molecularly imprinted polymers (MIPs) are macromolecular matrices that can mimic the functional properties of antibodies, receptors and enzymes while possessing higher durability. As such, these polymers are interesting materials for applications in biomimetic sensor, drug synthesis, drug delivery and separation. In this study, we prepared MIPs and molecularly imprinted nanospheres (MINs) as re...

Molecularly imprinted polymers were prepared and tested in different way. 1-methyl-2-piperidinoethylester of 4-decyloxyphenylcarbamic acid was used as template for imprints formation. Acrylamide, 4-vinylpyridine methacrylic monomers methanol acetonitrile a porogene used. Non-imprinted (NIP) each polymer by the same procedure. Polymers employed sorbents solid-phase extraction (SPE). In this work...
