“… HPLC on MIP columns [39,[44][45][46]  Solid phase extraction (SPE or MISPE) [47,48]  Membrane separations [49][50][51]  Sensors [52][53][54]  Binding assays [55][56][57]  Selective removal of low concentration contaminants in industrial or environmental technologies [5,8,9] In all of these applications selective separation or detection are needed. If selectivity between widely different compounds or groups of compounds is required, MIPs are suitable for any of the above tasks.…”

A simple and efficient method is presented for assessing molecularly imprinted polymers (MIP) and other sorbents from the point of view of practical applications. The adsorption isotherms of the compounds, which need to be separated or detected in an application, are constructed from a small number of measured points on a log-log chart and then are compared graphically. Despite its simplicity and robustness this method reveals the information needed for optimal selection between MIPs and alternative sorbents. The design of separation or detection methods with MIPs is also supported by the proposed graphical isotherm comparison. Many experimental isotherms are presented supporting the proposed method.

“…2d), and thus the hydrogen bonds made of MAA (H-O) could form a stronger interaction with other molecules than those of AN and MMA. Moreover, Beltran et al (2010) also reported that amongst functional monomers, MAA has been the most widely used functional monomer for MIP establishment. As a result, the MAA functional monomer was the best choice to construct the strong binding imprinted polymeric networks for the CLEN molecule, whereas AN and MMA did not perform effectively (Fig.…”

“…Several studies describe MAA monomers as having a great effect on binding adsorption (Shi et al, 2007;Beltran et al, 2010;He et al, 2010;Kang et al, 2012). Thus MAA-linked allyl-β-CD MIPs (M-MAA) were selected as models amongst the prepared MIPs to evaluate their binding performance for CLEN in different testing solvents.…”

“…MIPs, possessing the advantages of high selectivity, easy preparation, and high chemical stability, are synthetic polymers which display specific recognition sites for a target analyte (Mahony et al, 2005;Beltran et al, 2010;Prieto et al, 2011;Hiratsuka et al, 2013). MISPE cartridges have been employed to separate pesticides (Muldoon and Stanker, 1997;Zhu et al, 2002;Lv et al, 2007), drugs (Mullett and Lai, 1998;Shi et al, 2007), and illicit food additives (He et al, 2010;Kang et al, 2012) from different biological matrices.…”

A pre-treatment methodology for clenbuterol hydrochloride (CLEN) isolation and enrichment in a complex matrix environment was developed through exploiting molecularly imprinted polymers (MIPs). CLEN-imprinted polymers were synthesized by the combined use of ally-β-cyclodextrin (ally-β-CD) and methacrylic acid (MAA), allyl-β-CD and acrylonitrile (AN), and allyl-β-CD and methyl methacrylate (MMA) as the binary functional monomers. MAA-linked allyl-β-CD MIPs (M-MAA) were characterized by Fourier transform-infrared (FT-IR) spectroscopy and a scanning electron microscope (SEM). Based upon the results, M-MAA polymers generally proved to be an excellent selective extraction compared to its references: AN-linked allyl-β-CD MIPs (M-AN) and MMA-linked allyl-β-CD MIPs (M-MMA). M-MAA polymers were eventually chosen to run through a molecularly imprinted solid-phase extraction (MISPE) micro-column to enrich CLEN residues spiked in pig livers. A high recovery was achieved, ranging from 91.03% to 96.76% with relative standard deviation (RSD) ≤4.45%.

“…Generally, gas chromatography-mass spectrometry (GC-MS) is the most frequently used analytical technique for PAHs [4][5][6]. However, because of the complexity of matrix and low content of PAHs, high efficiency clean-up and enrichment procedures are required prior to analysis [6][7][8]. Various pretreatment processes for the extraction and concentration of PAHs from water samples have been increasingly developed, such as liquid-phase microextraction (LPME) [9], solid-phase extraction (SPE) [10,11], stirring bar sorptive extraction (SBSE) [12], and solid-phase microextraction (SPME) [13].…”
