“…There are several advantages of on-line MISPE, such as reduction of the loss of analytes and the risk of contamination, shortened pretreatment time, decreased consumption of solvents, and improved reproducibility, which enhance detection sensitivity and increase the potential of automation. 409 The important influencing factor of online-MISPE is the performance of MIPs which should provide fast mass transfer and good permeability. Thus, several typical studies have been proposed and have focused on the synthesis of MIPs with improved properties as follows.…”

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).

“…After the sample loading and washing out interfering compounds (the analytes are preconcentrated by the MISPE column), the analytes are eluted by the HPLC mobile phase [98][99][100][101][102][103][104]. These research works mainly focused on the analytes of Sudan dyes [98], Para Red [99], riboflavin [100], fluoroquinolone antimicrobials [101], tetracycline antibiotic residues [102], triazine residues [103] and estrogens [104] in samples from the environment (e.g., water and soil) and food (e.g., tomato sauce, chili sauce, egg, and milk). Guo et al [105] synthesized chlorsulfuron-MIPs by using vinylimidazolium ionic liquid as functional monomer.…”

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.

“…On-line MIP-SPE pre-concentration methodology has also recently been used by Jing et al [6], for the determination of trace tetracycline antibiotics (TCs) in egg samples. This approach affords high-throughput analysis (18 min per sample), and also provides high sensitivity and selectivity with recoveries ranging between 91.6 and 107.6%, showing that efforts should continue to be made in this promising research area.…”

“…Consequently, in order to minimize the effect of all these possible interferences a selective clean-up step may be required. Higher specificity and selectivity together with satisfactory extraction efficiency can be obtained using sorbents based on molecularly imprinted polymers (MIPs) [6][7][8].…”
