In the last 10 years, we have witnessed an extensive development of instrumental techniques in analytical methods for determination of various molecules and ions at very low concentrations. Nevertheless, the presence of interfering components of complex samples hampered the applicability of new analytical strategies. Thus, additional sample pre-treatment steps were proposed to overcome the problem. Solid sorbents were used for clean-up samples but insufficient selectivity of commercial materials limited their utility. Here, the application of molecularly imprinted polymers (MIPs) or ion-imprinted polymers (IIPs) in the separation processes have recently attracted attention due to their many advantages, such as high selectivity, robustness, and low costs of the fabrication process. Bulk or monoliths, microspheres and core-shell materials, magnetically susceptible and stir-bar imprinted materials are applicable to different modes of solid-phase extraction to determine target analytes and ions in a very complex environment such as blood, urine, soil, or food. The capability to perform a specific separation of enantiomers is a substantial advantage in clinical analysis. The ion-imprinted sorbents gained interest in trace analysis of pollutants in environmental samples. In this review, the current synthetic approaches for the preparation of MIPs and IIPs are comprehensively discussed together with a detailed characterization of respective materials. Furthermore, the use of sorbents in environmental, food, and biomedical analyses will be emphasized to point out current limits and highlight the future prospects for further development in the field.

“…Theophylline MIPs were first prepared using a non-covalent method by Mosbach et al [ 7 ] in 1993, which greatly promoted the development of MIT. Now, MIPs are widely used in sensors [ 8 , 9 ], chromatographic separation [ 10 , 11 ], and solid-phase extraction [ 12 , 13 ]. With the rapid development of quantum chemistry, more and more researchers are rapidly screening functional monomers, cross-linkers, solvents, and optimal imprinted ratios by computer simulation of MIPs systems [ 14 , 15 , 16 ].…”

Computer simulations are widely used for the selection of conditions for the synthesis of molecularly imprinted polymers and can rapidly reduce the experimental cycle time and save labor and materials. In this paper, estrone molecularly imprinted polymers (E1-MIPs) are designed at the M062X/6-311+G(d,p) level with itaconic acid (IA) as the functional monomer. The imprinted molar ratio between E1 and IA was optimized, cross-linkers and solvents were screened, and the nature of interactions between E1 and IA was explored. The simulated results showed that pentaerythritol triacrylate was the best cross-linker. Meanwhile, when the imprinted molar ratio between E1 and IA was 1:4, the E1–IA complex had the largest amount of hydrogen bonds, the lowest binding energy, and the strongest stability. Using the simulation results as guidance, the E1-MIPs were prepared to modify the electrons of a quartz crystal microbalance (QCM) sensor. The experimental studies showed that the E1-MIPs-QCM sensor had the highest adsorption capacity to E1 in comparison with their analogues, and the lowest detection value of the sensor was 16.00 μg/L. The computer simulations and experimental studies could provide guidance for synthesize novel E1-MIPs materials. It also could provide important references and directions for the application of E1-MIPs.

In this present study molecularly imprinted polymers were synthesized and characterized in order to extract caffeine from different food and beverage samples. The characteristics of molecular recognition of these polymers were used to develop a MIP-SPE methodology, a pre treatment able to eliminate interferences. The accuracy of the proposed method reached 96,4 ± 4,7% and the intermediate precision 2.30%. MIP-SPE cartridges here produced can be reused for at least 3 cycles, being much more affordable than the traditional commercial SPE cartridges. Caffeine was analyzed in fifteen food and beverage samples by the here developed method. It is particularly interesting to emphasize that the analyses of soft drinks and coffee powder samples made it possible to attest that, for this sort of samples, the proposed method is able to completely eliminate all the interferences present in these matrices, being unnecessary to apply chromatographic separation previously to analyte quantification. This result assures the method's selectivity and turns its application to these samples much faster,
