Non-enzymatic nanocomposites and their modified electrodes, including carbon nanotubes, graphene, metal nanoparticles, oxides, conductive polymers, MOFs derivatives, molecularly imprinted polymers are discussed in the rapid electrochemical sensing of OPPs.

a chelating resin is prepared by condensation polymerization of aniline with formaldehyde andcharacterized by ft-ir, elemental analysis and studied for the preconcentration and determination of traceplatinum ion from environmental water sample using inductively coupled plasma-atomic emission spectroscopy(icp-aes). the optimum ph value for sorption of the metal ions was 5. the maximum adsorption...

Polymers can be prepared using chemical and/or electrochemical methods of polymerization (see Chap. 2), although most redox polymers have been synthesized by chemical polymerization. Electrochemically active groups are either incorporated into the polymer structure inside the chain or included as a pendant group (prefunctionalized polymers), added to the polymer phase during polymerization, or ...

Molecular recognition is a fundamental and ubiquitous process that is the driving force behind life. Natural recognition elements - including antibodies, enzymes, nucleic acids, and cells - exploit non-covalent interactions to bind to their targets with exceptionally strong affinities. Due to this unparalleled proficiency, scientists have long sought to mimic natural recognition pathways. One p...

As known, in the synthesis of conductive polyaniline polymer from aniline monomer, polymerization medium must be acidic. In order to make acidic, protonic acids such as HCl and H2SO4 are generally used. this study, two have been used One them, we know, is a acid. The other acid zinc ion, which Lewis metal ion has never for purpose up now. Two polymers synthesized prove that can also presence io...

The interactions of aniline with soil at an industrial spill site were investigated. Sorption of aniline to the soil was observed to occur through a two-step mechanism. The first step was an ion exchange process with the protonated amine serving as an organic cation. This step was influenced by solution pH and ionic composition. The second step was covalent bonding most likely with quinone moie...

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...
