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...

Mechanisms of interaction of a three-dimensional polymer with solutes are of interest in the development and function of synthetic biomimetic polymers. We have investigated the effects of template/monomer interactions and template concentration on conversion and polymerization rates of a molecularly imprinted polymer. Copolymers of 2-hydroxyethyl methacrylate (HEMA) and poly(ethylene glycol) di...

Molecularly imprinted photonic polymers can serve as ideal sensing elements for efficiently creating cross-reactive sensor arrays. Based on this concept, a new method for sensitive and label-free detection of challenging PBDEs was developed, by which the direct detection and discrimination of trace levels of PBDEs against a high-background of interferents was achieved with 100% accuracy.

We describe an original approach to graft molecularly imprinted polymers around gold nanorods by combining the diazonium salt chemistry and the iniferter method. This chemical strategy enables fine control of the imprinting process at the nanometer scale and provides water-soluble plasmonic nanosensors.

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...

In recent years, plasmonic sensors have been used in various fields ranging from environmental monitoring, pharmaceutical analysis, medical diagnosis, and food quality assessment to forensics. A significant amount of information on their applications already exists there is a continuing development reliable, selective, sensitive, low-cost sensors. Combining molecularly imprinting technology wit...

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...

Background and purpose: Cytotoxic drugs are a group of chemicals that raise concerns over the health of healthcare professionals. Therefore, accurate methods are needed to investigate the traces of these drugs. This study was done to fabricate and optimize molecularly imprinted membrane as a specific absorbent in assessment of occupational exposure to 5-fluorouracil. Materials and methods: 5-F...
