Considering the importance of developing a new analytical approach for pesticide residue detection for the sake of ensuring food safety, a β‐cyclodextrin based molecularly imprinted polymer was prepared for selective determination of carbendazim. The polymers consist of a porous and hollow structure demonstrating the selective abundant adsorption sites for carbendazim molecule. The selectivity and adsorption capacity of the imprinted polymers were analyzed with dispersive solid‐phase extraction and analyzed with high performance liquid chromatography coupled with ultraviolet. The results of imprinted polymers were higher than non‐imprinted polymers with the maximum adsorption capacity of 3.65 mg/g within 30 min of total adsorption time. The reusability of the imprinted polymers was determined to evaluate its effectiveness and stability, which proved that the polymers lost 10% efficiency within seven consecutive recycles. The developed method displayed good linearity over the concentration range of 0.05–2.0 mg/L. The recovery percentage of 81.33–97.23 with relative standard deviations of 1.49–4.66% was obtained from spiked apple, banana, orange, and peach samples with a limit of detection of 0.03 mg/L and a limit of quantification of 0.10 mg/L (signal to noise ratio = 3/10). The overall performance of the proposed method evident that this technique provided a desirable outcome and it can be used as a convenient approach, as it qualifies the analytical standards.

“…Currently, the aforementioned polymerization methods (Table 4 ) are being modified to improve the properties of the molecularly imprinted polymers which include strategies deploying dual functional monomers (Zhao et al 2019 ; Ut Dong et al 2021 ), ultrasound-assisted precipitation polymerization (Abdullah et al 2019 ), the use of a dual template (Lu et al 2019 ), microwave-assisted emulsion polymerization (Chen et al 2015 ), and microwave-assisted heating (Fu et al 2015 ). Furthermore, the traditional polymerization techniques are also upgraded by newer techniques, including green chemistry concepts, with the use of deep eutectic solvents (Li and Row 2019 ), supercritical carbon dioxide (Byun et al 2013 ), and ionic liquids (Viveiros et al 2018 ; Liu et al 2021a ).…”

The release of pharmaceuticals into the environment induces adverse effects on the metabolism of humans and other living species, calling for advanced remediation methods. Conventional removal methods are often non-selective and cause secondary contamination. These issues may be partly solved by the use of recently-developped adsorbents such as molecularly imprinted polymers. Here we review the synthesis and application of molecularly imprinted polymers for removing pharmaceuticals in water. Molecularly imprinted polymers are synthesized via several multiple-step polymerization methods. Molecularly imprinted polymers are potent adsorbents at the laboratory scale, yet their efficiency is limited by template leakage and polymer quality. Adsorption performance of multi-templated molecularly imprinted polymers depends on the design of wastewater treatment plants, pharmaceutical consumption patterns and the population serviced by these wastewater treatment plants.

“…In this case, scCO 2 -assisted polymerization was shown to be more efficient at selectively separating and detecting templates than the other polymerization processes. BPA and 2,4-dichlorophenoxyacetic acid-imprinted polymers were also reported by Byun et al [ 34 ], in which MIPs were prepared by dispersion polymerization in scCO 2 , using MAA as functional monomer, EGDMA as the crosslinker, and poly(heptadecafluorodecyl methacrylate) (PHDFDMA) as a dispersing agent, obtaining particles with 300 nm. BPA and 2,4-dichlorophenoxyacetic acid, an herbicide compound, are typically present in aqueous solutions.…”

Molecular imprinting is a powerful technology to create artificial receptors within polymeric matrices. Although it was reported for the first time by Polyakov, eighty-four years ago, it remains, nowadays, a very challenging research area. Molecularly imprinted polymers (MIPs) have been successfully used in several applications where selective binding is a requirement, such as immunoassays, affinity separation, sensors, and catalysis. Conventional methods used on MIP production still use large amounts of organic solvents which, allied with stricter legislation on the use and release of chemicals to the environment and the presence of impurities on final materials, will boost, in our opinion, the use of new cleaner synthetic strategies, in particular, with the application of the principles of green chemistry and engineering. Supercritical carbon dioxide, microwave, ionic liquids, and ultrasound technology are some of the green strategies which have already been applied in MIP production. These strategies can improve MIP properties, such as controlled morphology, homogeneity of the binding sites, and the absence of organic solvents. This review intends to give examples reported in literature on green approaches to MIP development, from nano-to micron-scale applications.
