“…The electrochemistry methods [40,41] show low detection limit and broad linear range, but possibly involve the disadvantages of instability and interference of organics in anodic/catholic stripping voltammetry. Besides, magnetic MIPs for BPA followed by HPLC-fluorometry determination involve complicated sample treatment [24]. A molecularly imprinted fluorescent sensor using CdSe QD as signal transducer for BPA detection needs time-consuming synthesizing process [23].…”

“…So, MIPs with high selectivity are gaining popularity. Especially, MIPs based fluorescent detection for BPA has received increasing concerns [22][23][24]. For example, Kim et al prepared a molecularly imprinted fluorescent sensor by using a CdSe QD as a signal transducer for BPA analysis [23].…”

“…For example, Kim et al prepared a molecularly imprinted fluorescent sensor by using a CdSe QD as a signal transducer for BPA analysis [23]. In the meantime, Yuma et al prepared magnetic MIPs by a multi-step swelling polymerization method for BPA followed by HPLC-fluorometry detection [24]. As seen, the MIPs coupled with fluorometry strategies are more convenient with their excellent merits.…”

a b s t r a c tA flexible fluorescent sensing strategy for the recognition and detection of bisphenol A (BPA) has been proposed based on molecularly imprinted polymers (MIPs)-coated gold nanoclusters (AuNCs), by taking advantages of the high selectivity of MIPs and the strong fluorescence property of AuNCs. SiO 2 @AuNCs were initially prepared by making use of the powerful amido bonds between carboxyl-terminated AuNCs and amino-functionalized SiO 2 nanoparticles. Then MIPs-coated AuNCs were formed by anchoring MIP layer on the surface of SiO 2 @AuNCs via a sol-gel process. In the presence of imprinting template BPA, a Meisenheimer complex could be formed between BPA and the primary amino groups on the surface of the AuNCs, and the photoluminescent energy of AuNCs would be transferred to the complex, and thereby result in the fluorescence quenching of AuNCs. The fluorescence-quenching fractions of the sensor presented a satisfactory linearity with BPA concentrations over the range of 0-13.1 M and the detection limit could reach 0.10 M. Distinguished selectivity was also exhibited to BPA over other possibly competing molecules. Moreover, the sensor was successfully applied to determine BPA in seawater, and the average recoveries of BPA at three spiking levels ranged from 91.3 to 96.2% with relative standard deviations below 4.8%. This AuNCs-MIPs based sensor provided great potentials for recognition and determination of phenolic environmental estrogens in complicated samples.

A B S T R A C TSample preparation is a crucial bottleneck in the whole analytical process. Solid-phase sorbents (SPSs) have aroused increasing interest in research on sample preparation, as they have key roles in obtaining high clean-up and enrichment efficiency in the analysis of trace targets present in complex matrices. The objective of this review is to provide a broad overview of the recent advances and applications of SPSs in sample preparation prior to chromatographic analysis, during the period 2008-13. We include SPSs, such as molecularly-imprinted polymers, carbon nanomaterials, metallic nanoparticles and metal organic frameworks, focusing on solid-phase extraction, solid-phase microextraction, matrix solid-phase dispersion and stir-bar sorptive extraction of typical pollutants in environmental, biological, food and pharmaceutical samples. We propose remaining challenges and future perspectives to improve development of new SPSs and to apply them further.

“…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%.
