Membrane-protected molecularly imprinted polymers: Towards selectivity improvement of liquid-phase microextraction
نویسندگان
چکیده
Sample preparation is still considered the bottle-neck of whole analytical process. Nowadays, several sample techniques are available, however all them suffer from lack selectivity. At this regard, molecularly imprinted polymers (MIPs) excellent materials able to perform selective extractions. Recently, new objectives in have been set, including use smaller initial sizes; facilitate automation; and, minimize amount glassware and organic solvents needed. MIP incorporation other microextraction offers a strategy order fulfil current requirements. However, even using MIPs, complexity can affect recoveries target analytes, negatively affecting method precision accuracy. The porous membrane, as protective sleeve, one simplest approaches circumvent difficulties mentioned above analysis complex “dirty” samples. Accordingly, present paper pretends provide an overview micro-extraction developed during last years based on membrane-protected MIPs how such open pathways development liquid phase methods with improved characteristics. Advantages, drawbacks future expected trends also critically assessed.

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 کاملMolecularly 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...
