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.

Chemoresponsive Molecularly Imprinted Polymers

2022
In this chapter we explore molecularly imprinted polymers (MIPs) as both selective recognition elements and responsive materials in a wide variety of fields, focussing on drug delivery systems, sensor development and separation/purification purposes. The effects of physical and chemical stimuli on the polymer conformation are thoroughly discussed.

Food Analyses Using Molecularly Imprinted Polymers

Journal of Agricultural and Food Chemistry, 2001
Molecular imprinting technology (MIT) is a technique for generating polymers bearing biomimetic receptors. It offers several advantages to the agrofood industry in areas such as analysis, sensoring, extraction, or preconcentration of components. It has the potential of becoming a tool for acquiring truly simple, rapid, and robust direct measurements ...

Molecularly Imprinted Polymer-Based Biosensors

2013
Molecular imprinting is a versatile technique for the preparation of synthetic receptors, on the basis of complexes between a template molecule and polymerizable monomers. After polymerization process, the products are called molecularly imprinted polymers (MIPs).
