“…This rapid adsorption behavior could be explained by multiple interactions between [VCIM]Cl and L-Phe because multiple interactions were more efficient. A similar observation has also been reported in the literatures by Qian [35] and Luo. [32] However, it is difficult for many MIPs formed by simple interactions, such as hydrogen-bonding interactions between functional monomers and template, to achieve adsorption equilibrium in short time just as the work of Li.…”

L-Phenylalanine (L-Phe) imprinted polymers (L-MIPs) were prepared via precipitation polymerization using 1-vinyl-3-carboxymethylimidazolium chloride ([VCIM]Cl) as functional monomer, which could interact with L-Phe through electrostatic interactions, hydrogen-bonding, and π-π interactions. The morphologies of obtained polymers were observed by a scanning electron microscope, and their structures were analyzed by Fourier transform infrared spectroscopy. The effects of monomer species and molar ratio of template to functional monomer or crosslinker on adsorption capacity and imprinting factors (

“…Our group put more emphasis on the protein conformation integrity during imprinting process. Qian et al has developed a way of using specific ionic liquid as protein structure stabilizer to prepare temperature‐responsive imprinted hydrogel . According to Hofmeister effect, they designed a kind of ionic liquid composed of chaotropic cation and kosmotropic anion to stabilize the protein secondary structure, defined as [VAFMIM]Cl.…”

Molecular imprinting is an approach of generating imprinting cavities in polymer structures that are compatible with the target molecules. The cavities have memory for shape and chemical recognition, similar to the recognition mechanism of antigen–antibody in organisms. Their structures are also called biomimetic receptors or synthetic receptors. Owing to the excellent selectivity and unique structural predictability of molecularly imprinted materials (MIMs), practical MIMs have become a rapidly evolving research area providing key factors for understanding separation, recognition, and regenerative properties toward biological small molecules to biomacromolecules, even cell and microorganism. In this review, the characteristics, morphologies, and applicability of currently popular carrier materials for molecular imprinting, especially the fundamental role of hydrogels, porous materials, hierarchical nanoparticles, and 2D materials in the separation and recognition of biological templates are discussed. Moreover, through a series of case studies, emphasis is given on introducing imprinting strategies for biological templates with different molecular scales. In particular, the differences and connections between small molecular imprinting (bulk imprinting, “dummy” template imprinting, etc.), large molecular imprinting (surface imprinting, interfacial imprinting, etc.), and cell imprinting strategies are demonstrated in detail. Finally, future research directions are provided.

“…During the past few years, ionic liquids (ILs) have received much attention, due to their unique properties, such as non‐volatility, non‐flammability, high ion density, high ionic conductivity, and enhanced dispersibility in inorganic/organic solvents . Recently, ILs are recognized as functional monomers in the preparation of MIPs, which can be utilized in an aqueous environment . This is due to the functional groups of ILs, which could adsorb analytes through π–π interaction, electrostatic attraction, hydrogen bonding interaction, and dipole–dipole interaction.…”

A new type of molecularly imprinted ionic liquid magnetic microspheres was synthesized by aqueous suspension polymerization, using 4,4'-dichlorobenzhydrol as a dummy template, and 1-allyl-3-ethylimidazolium hexafluorophosphate and methacrylic acid as co-functional monomers. The results of morphology and magnetic property evaluation of the obtained microspheres demonstrated that it was monodispersed spherical, possessed a rough surface, and an outstanding magnetic properties. Binding experiments revealed that it had a substantial adsorption capacity and strong recognition ability to organochlorine pesticides (OCPs) in aqueous solution. Then the microspheres were applied as an adsorbent of magnetic dispersive solid-phase extraction for the selective recognition and rapid determination of OCPs in environmental water. Under the optimum conditions, good linearity of the three types of OCPs (dicofol, tetradifon, and p,p'-dichlorodiphenyldichloroethane) was achieved in the range of 1.0-100 ng/mL (r ≥ 0.9994). The recoveries at three spiking levels ranged from 82.6 to 100.4% with the RSDs less than 6.9%.
