Molecularly imprinted polymers.

Ceska a Slovenska farmacie : casopis Ceske farmaceuticke spolecnosti a Slovenske farmaceuticke spolecnosti, 2012
Nowadays about 28 million different simple or complex chemical entities are known. Today we cannot imagine the life without different kinds of drugs, cosmetics, pesticides, food additives or stimulants. In the recent period in the field of analytical chemistry or pharmacy more modern techniques or methodologies are required which will allow selective ...

Molecularly Imprinted Polymers

2016
The idea of using molecular imprinted materials as catalysts was originally to translate the basic understanding and functionality of natural enzymes to synthetic polymers, thus developing low-cost, stable, and efficient biomimetic catalysts. The design of imprinted cavities can be tailored according to stable transition state analogs and by precisely ...

Molecularly Imprinted Polymers

2011
Molecular imprinting is a process that allows for the synthesis of artificial receptors for a given target molecule based on synthetic polymers. The target molecule acts as a template around which interacting and cross-linking monomers are arranged and co-polymerized to form a cast-like shell. In essence, a molecular memory is imprinted in the polymer,

Restricted Access Molecularly Imprinted Polymers

2021
The use of conventional molecularly imprinted polymers (MIPs) for biological sample preparation is a difficult procedure due to the presence of high concentrations of proteins which can obstruct the selective binding sites, decrease the adsorption capacity, and compromise the analytical validation.

Molecularly imprinted polymers

Despite continuous advances in analytical instrumentation, sample preparation remains one of the most crucial steps in an analytical process. In this regard, efforts have been made to improve selectivity during extraction and/or subsequent cleanup of sample extracts.

Molecularly Imprinted Polymers

Chemical Reviews, 2018
Molecularly imprinted polymers are synthetic receptors for a targeted molecule. As such, they are analogues of the natural antibody-antigen systems. In this review, after a recounting of the early history of the general field, we specifically focus on the application of these polymers as sensors.

Molecularly Imprinted Polymers

2004
Molecularly imprinted polymers (MIPs)1–4 are highly stable polymeric molds that possess selective molecular recognition properties for various kinds of molecules. MIPs consist of highly crosslinked polymers that are synthesized in the presence of a template (imprint) molecule.

Molecularly imprinted polymer sensor arrays

Current Opinion in Chemical Biology, 2010
The sensor array format has proved an effective method of transforming sensors of modest selectivity into highly selective and discriminating sensors. The primary challenge in developing new sensor arrays is collecting together a sufficient number of recognition elements that possess different binding affinities for the analytes of interest.

Janus molecularly imprinted polymer particles

Chem. Commun., 2014
Janus MIP particles were synthesized via a wax–water Pickering emulsion. The MIP microtransporter concept provided the Janus MIP particles with attractive capabilities for autonomous binding and controlled drug delivery.
