Molecular imprinting polymers (MIPs), generally considered as artificial mimics that are comparable to natural receptor, are polymers with tailor‐made specific recognition sites complementary to the template molecules in shape and size. As a class of supramolecular compounds, cyclodextrins (CDs) are flourishing in the field of molecular imprinting with their unique structural properties. This review presents recent advances in application of MIPs based on CDs during the past five years. The discussion is grouped according to the different role of CDs in MIPs, that is, functional monomer, carrier modifier, etc. Main focus is the application of CD‐based MIP on sample preparation, detection, and sensing. Additionally, drug delivery with CD‐based MIP is also briefly discussed. Finally, challenges and future prospects of application of CDs in MIP are elaborated.

“…To check the superior adsorption performance of MIMs with amphiphilic ILs as the surfactant to control pore size and immobilize template, we investigated the adsorption capacity and the equilibrium rate of MIMs for Cyt c in other related researches. As shown in Table 4 , owing to advantages of the high specific surface areas of mesoporous silica and the epitope imprinting method, this new imprinting strategy could obtain much higher binding capacity toward Cyt c than that of others imprinted polymers [ 36 , 37 , 38 ]. From the comparison of the adsorption rate, we could conclude that this approach still displayed the rapid adsorption equilibrium on the basis of a superior adsorption capacity.…”

Molecularly imprinted mesoporous materials (MIMs) were synthesized to improve the adsorption performance of Cytochrome c (Cyt c) by using an imidazolium-based amphiphilic ionic liquid 1-octadecyl-3-methylimidazolium chloride (C18MIMCl) as surfactant in aqueous solution via the epitope imprinting approach. The surface-exposed C-terminus nonapeptide of Cyt c (residues 96–104, AYLKKATNE) was utilized as the imprinted template. The nitrogen adsorption-desorption, thermo-gravimetric analysis, and transmission electron microscopy verified the successful preparation of MIMs with ordered mesoporous structure. The adsorption isotherm studies showed that the obtained MIMs exhibited superior adsorption capacity toward Cyt c of 86.47 mg·g−1 because of the high specific surface areas of 824 m2·g−1, and the appropriate pore size promoted the mass transfer of Cyt c, causing a rapid adsorption equilibrium within 20 min. Furthermore, these MIMs still remained excellent selectivity and recognition ability according to the selective as well as the competitive adsorption studies, suggesting that the molecularly imprinted mesoporous materials is expected to be used in the field of highly efficient separation and enrichment of proteins.

“…Especially, the derivative synthesized ionic liquid as a functional monomer in the molecularly imprinted polymeric ionic liquid (MIPIL) can efficiently enhance the selective recognition ability with low detection limit and rapid detection rate 22 . As their wide electrochemical window, good biocompatibility, phase transfer catalyst, and high ionic conductivity, ILs were introduced in the preparation of MMIP to obtain the anticipate activity 23 . At the same time, the appropriate ILs in the MMIPIL performed a very good dispersion of Fe 3 O 4 and enhanced the marching signal of target molecules.…”

A High-matched Melamine Sensor Using Core/shell Nano Particles of Fe3O4@Polyrutin–COOH and Ionic Liquid as Imprinted Polymeric Monomers

Herein, a magnetic molecular imprinted polymeric ionic liquid (MMIPIL) film was designed by using the functionalized ionic liquid (3-vinyl-4-amino-5imidazole carboxamide chloride, IL) and Fe 3 O 4 @Polyrutin-COOH as functional monomer and supporting materials. The change in the direction of the charge density in the structure of MMIPIL polymer resulted in a red shift about 100nm for the characteristic group of-C=O. Polyrutin containing electron-rich benzene ring and multiple hydroxyl groups not only prevented the aggregation of Fe 3 O 4 , but also benefitted to immobilize template molecules. The more symmetric amino groups in template molecules generated more hydrogen bonds and other synergistic effects between MEL and functional monomers, which resulted in a high-matched and high stable MMIPIL sensor. The proposed magnetic sensor lowered the matching potential, and enhanced the signal for the detection of melamine (MEL) in milk powder. Under the optimum conditions, the MEL template molecule showed a significant linear relationship between 5.0×10-3 and 0.8 µg/L with a detection limit (S / N = 3) of 1.5× 10-3 µg/L. The MMIPIL sensor showed wonderful selectivity and exhibited facile, fast and efficient results in the monitoring MEL with the recoveries between 96.5% and 108.3%.
