a Molecular imprinting technology (MIT), often described as a method of making a molecular lock to match a molecular key, is a technique for the creation of molecularly imprinted polymers (MIPs) with tailor-made binding sites complementary to the template molecules in shape, size and functional groups. Owing to their unique features of structure predictability, recognition specificity and application universality, MIPs have found a wide range of applications in various fields. Herein, we propose to comprehensively review the recent advances in molecular imprinting including versatile perspectives and applications, concerning novel preparation technologies and strategies of MIT, and highlight the applications of MIPs. The fundamentals of MIPs involving essential elements, preparation procedures and characterization methods are briefly outlined.Smart MIT for MIPs is especially highlighted including ingenious MIT (surface imprinting, nanoimprinting, etc.), special strategies of MIT (dummy imprinting, segment imprinting, etc.) and stimuli-responsive MIT (single/dual/ multi-responsive technology). By virtue of smart MIT, new formatted MIPs gain popularity for versatile applications, including sample pretreatment/chromatographic separation (solid phase extraction, monolithic column chromatography, etc.) and chemical/biological sensing (electrochemical sensing, fluorescence sensing, etc.). Finally, we propose the remaining challenges and future perspectives to accelerate the development of MIT, and to utilize it for further developing versatile MIPs with a wide range of applications (650 references).

“…3) either non-imprinted or imprinted with monocrotophos, and its sorption characteristics and applications as a high selective extraction technique for organophosphorus pesticides (OPPs) were evaluated [25]. Hu et al [26] published the preparation characteristics and applications of a sorptive stir bar coated with MIP using triadimefon as the template molecule. The MIP-coated stir bar has been coupled with HPLC for simultaneously multi-residue monitoring of eight triazole fungicides (triadimefon, triadimenol, diniconazole, flutriafol, hexaconazole, tebucomazole, paclobutrazole, and uniconazole) residual in soil.…”

Summary. Stir bar sorptive extraction (SBSE) is an extraction technique for enrichment of organic compounds from aqueous and gaseous matrices. This technique is based on sorptive extraction, whereby the solutes are extracted into a polymer coating on magnetic stirring rod. SBSE has been used in various types of analytical procedures and wide variety of matrices. However, a limitation of SBSE lies in the fact that only polydimethylsiloxane (PDMS)-coating material is commercially available and that PDMS predominantly extracts non-polar compounds with K o/w higher than 10. In this survey, a review on non-PDMS stir bar sorptive extraction coatings and their applications to the analysis of environmental, food, and biomedical samples is given.

“…Table 2 summarizes some new applications of MIPs as SPSs in the three extraction methods. For SPME, the MIPs are usually coated on a fiber segment, and then the fiber is inserted into the SPME device for the extraction [111][112][113][114][115][116][117][118][119][120][121][122][123][124][125][126]. Sometimes, nanomaterials can be combined with MIPs in order to modify the extraction efficiency {e.g., CNTs [112,117]}.…”

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.
