Molecularly Imprinted Polymers for Sample Preparation
The sample treatment/preparation steps involve any operation and manipulation of the samples prior to instrumental determination of the target compounds [1−3]. This is a critical step in the analytical process because the concentration of target analytes in the samples is frequently too low for quantification. Thus, the first step of the preparation protocol involves the exhaustive extraction/c...
متن کاملPreparation of highly selective solid-phase extractants for Cibacron reactive dyes using molecularly imprinted polymers.
Selective polymeric extractants were prepared for preconcentration of Cibacron reactive red dye, a dye that is often applied with Cibacron reactive blue and Cibacron reactive yellow for dyeing of fabrics. The best extractant was fabricated (in chloroform) using methacrylic acid (as monomer), ethylene glycol dimethacrylate (as crosslinker), AIBN (as initiator for polymerization), and red dye as ...
متن کاملCitrinin selective molecularly imprinted polymers for SPE.
Molecularly imprinted polymers (MIPs) for citrinin (Cit) with 1-hydroxy-2-naphthoic acid (HNA) as mimic template were prepared and the molecularly imprinted SPE method was developed for the detection of Cit in rice with HPLC. The adsorption properties of HNA and Cit on the MIPs and nonimprinted polymers were investigated. It proved that MIPs showed higher selectivity adsorption to HNA and Cit t...
متن کاملComputational Design of Molecularly Imprinted Polymers
Artificial receptors have been in use for several decades as sensor elements, in affinity separation, and as models for investigation of molecular recognition . Although there have been numerous publications on the use of molecular modeling in characterization of their affinity and selectivity, very few attempts have been made on the application of molecular modeling in computational design of ...
متن کاملMolecularly Imprinted Polymers: Present and Future Prospective
Molecular Imprinting Technology (MIT) is a technique to design artificial receptors with a predetermined selectivity and specificity for a given analyte, which can be used as ideal materials in various application fields. Molecularly Imprinted Polymers (MIPs), the polymeric matrices obtained using the imprinting technology, are robust molecular recognition elements able to mimic natural recogni...
