“…211 Compared to the above methods, the sol-gel process has distinct advantages such as the ease of fabrication at room temperature and the use of eco-friendly reaction solvents, ultrapure water or ethanol. [232][233][234][235][236][237][238][239] Zhu et al 233 combined the grafting method and the sol-gel process to prepare M-MIPs for bovine hemoglobin (BHb) recognition. Fe 3 O 4 nanospheres were directly functionalized with amine groups.…”

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).

“…4B and C), with the equations of ln(Q e −Q t ), = −k 1 t+lnq e and t/Q t = (k 2 Q e 2 )−1+t/Q e , respectively (where Q t is the adsorption capacity of the polymer at But the correlation coefficients of the pseudo-second order kinetic model is higher than that the correlation coefficients of the pseudo-first order kinetic model which shows that the adsorption kinetics of MIP on acid amide compounds is better agreement with the pseudo-second order kinetic model. Further indicating that MIP adsorption to acid amide components is a suitable chemical adsorption process because of the hydrogen bond force and hydrophobic interaction of the components and the polymer [28,29].…”

Molecularly imprinted polymers were prepared using the molecular structure analogs of sanshool as template molecule, 2-vinylpyridine and β-cyclodextrin as double functional monomers, ethylene dimethacrylate as cross linker, and azobisisobutyronitrile as initiator. The structural characteristics of the polymers were determined by Fourier-transform infrared spectroscopy and scanning electron microscopy. Dynamic adsorption and isothermal adsorption were also investigated. The molecularly imprinted polymers were used to prepare a molecularly imprinted solid-phase extraction column in order to separate acid amide components from pepper oil resin derived from Chinese prickly ash (Zanthoxylum bungeanum). After eluting, the percentage of acid amide components was enhanced to 92.40 ± 1.41% compared with 23.34 ± 1.21% in the initial pepper oil resin, indicating good properties of purification of molecularly imprinted polymers and potential industrial application.

“…Boronic acids can bind cis-diol-containing compounds covalently based on boronate affinity interaction at a high pH value while the boronate esters dissociate at a relatively low pH value. [36][37][38][39][40][41][42][43] Magnetic Fe 3 O 4 nanoparticles (MNPs), [44][45][46][47][48][49][50][51][52][53] due to their low cost, magnetic susceptibility, low toxicity and good biocompatibility, can be well used as supporting materials. In recent years, magnetic nanoparticles (MNPs) such as imprinted MNPs, metal-chelated MNPs and other functional MNPs have widespread applications in different areas including protein purification, solid-phase extraction, energy, biomedicine, environmental fields, bioimaging, waste water treatment, and immobilisation of cells and enzymes.…”
