Correction for 'Quantum dot-imprinted polymers with size and shell-selective recognition properties' by S. Gam-Derouich et al., Chem. Commun., 2015, DOI: 10.1039/c5cc05203c.
The relationship between molecularly imprinted polymer (MIP) morphology and template-rebinding over a series of warfarin-imprinted methacrylic acid co(ethylene dimethacrylate) polymers has been explored. Detailed investigations of the nature of template recognition revealed that an optimal template binding was obtained with polymers possessing a narrow population of pores (~3-4 nm) in the meso...
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...
Molecular imprinting has proved to be an effective technique for generating specific recognition sites in synthetic nanopolymers. These sites are tailor-made in situ by copolymerization of functional monomers and cross-linked around the template molecules. The print molecules are subsequently extracted from the polymer, leaving accessible complementary binding sites in the polymer network. Desp...
In this work, the template, monomer, and cross-linker with the ratio of 1:8:40 were used to synthesize Molecularly Imprinted Polymers (MIPs) for extraction of the bioactive chemical compounds from some traditional herbs as a sorbent material. Quercetin, Methacrylic Acid (MAA), Trimethylolpropanetrimethacrylate (TRIM) and Tetrahydrofuran (THF) were used as a template, funct...
Molecularly imprinted polymers for dimethoate recognition were synthesized by the precipitation polymerization technique using methyl methacrylate (MMA) as the functional monomer and ethylene glycol dimethacrylate (EGDMA) as the cross-linker. The morphology, adsorption and recognition properties were investigated by scanning electron microscopy (SEM), static adsorption test, and competitive ads...
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...
با انجام واکنش پلیمری شدن رادیکالی در حضور کاتچین(+)، آکریلیک اسید، تریمتیلول پروپان تری متاکریلات به ترتیب بهعنوان مولکول هدف، منومر عاملدار، اتصال دهنده عرضی (به نسبت 1:20:80) در حلال استونیتریل، شبکه سه بعدی پلیمرهای قالب مولکولی (MIPs) سنتز گردید. طی فرآیند استخراج، مولکول هدف جدا شده و بدین ترتیب شبکه پلیمری نانو حفره قالب دار شده تهیه شد که قادر است به صورت گزینشی ماده زیست فعال کاتچین ...
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 ...
