“…For the effective removal of organic thiophene sulfides in the vehicle fuel oil, Hua et al. [ 87 ] fabricated MIPs with β‐CD as the carbon source and five unsaturated polycarboxylic acids as the functional monomer respectively. First, porous carbon nanospheres (PCNS‐5) were prepared by hydrothermal method using β‐CD as raw material, and then surface molecularly imprinted polymers were prepared on the surface.…”

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.

“…Polymer-based sensors possessing high chemical and thermal stability, biocompatibility, and low cost have been used to develop highly selective sensors. − They often are functionalized for selective capture of analyte molecules through complexation or ion exchange mechanisms. , An interesting way of introducing selectivity is polymerization in the presence of an analyte/template molecule. The removal of the template molecules leaves a substrate called a molecularly imprinted polymer (MIP) with the cavities consisting of binding sites that are complementary in physical (size and shape) and chemical (functionality and chemical structure) properties to that of the template molecules. − MIPs are emerging as a promising platform for the electrochemical detection of electrochemically inactive molecules (molecules that are not easily oxidizable or reducible within potential windows of water) …”

Quantifying Interferent Effects on Molecularly Imprinted Polymer Sensors for Per- and Polyfluoroalkyl Substances (PFAS)

Per- and polyfluoroalkyl substances (PFAS) are emerging as harmful environmental micropollutants. Generally, PFAS species are quantified by mass spectrometry, for which a collected sample is taken to a centralized facility. Robust techniques to quantify PFAS in the field are necessary to diagnose environmental contamination at the earliest onset of pollution. Here, we developed a molecularly imprinted polymer (MIP) electrode for the detection of perfluorooctanesulfonate (PFOS) and explored the MIP surface and the effects of interfering molecules. MIPs were formed by the anodic deposition of o-phenylenediamine (o-PD) in the presence of PFOS template molecules on a glassy carbon macroelectrode. The performance of the resulting MIP electrode was evaluated by the current obtained from the oxidation of ferrocene carboxylic acid as the electrochemical probe. The MIP electrode was able to detect PFOS with a detection limit of 0.05 nM, which is lower than the health advisory limit of 0.14 nM reported by the U.S. EPA. To better understand PFOS association into the MIP, a Langmuir binding model was developed based on the changes in electrochemical responses of the MIP. Fitting the model to the experimental data gave an association constant (K A ) of 4.95 × 1012 over a PFOS concentration range of 0 to 0.05 nM. The binding isotherm of other commonly found substances in contaminated water sources such as chloride, humic acid, perfluorooctanoic acid (PFOA), and perfluorobutanesulfonate (PFBS) was also investigated. In the case of chloride and humic acid, the calculated K A values of 9.05 × 107 and 6.01 × 105, respectively, indicate relatively weak adsorption of these species on the MIP. However, PFOA, which is the carboxylate analog of PFOS, revealed a very close K A value (3.41 × 1012) to PFOS. A greater K A value (1.43 × 1013) was obtained for PFBS, which possesses the same functional group and a smaller molecular size compared to PFOS. The presented platform emphasizes the necessity to develop new strategies to make MIP sensors more specific if practical applications are to be pursued.

This review describes the synthesis of nanocomposite derivatives based on β‐cyclodextrin (β‐CD) using silver nanoparticles (NPs), gold NPs, magnetic NPs, carbon nanotubes, nanosheets, carbon dots and graphene oxide NPs. These nanocomposites were prepared by green synthesis method, chemical method, reduction method, thermal reduction, ultrasonication method and hydrothermal method. β‐CD is cyclic oligosaccharide consisting of seven glucose units linked by 1,4‐α‐glycosidic bonds. Its external surface is hydrophilic due to the substantial hydroxyl groups, and the interior is hydrophobic. β‐CD are useful in nanocomposites and metallic NPs because they provide nanoplatforms for biocompatibility. β‐CD is commonly used to change NPs because of their excellent biocompatibility, amphipathic properties and for enhancing the morphological and chemical features of nanocomposites. Thus, nanostructured materials based on β‐CD may enhance the potential for molecular recognition property which is a natural phenomenon and fundamentally important in chemistry and biology. The most important area in molecular recognition research is design and synthesis of model receptors (hosts) to recognize substrates (guests) of biochemical significance to mimic biological events. Because NPs have a high surface‐to‐volume ratio when combined with molecularly imprinted polymers (MIPs). This review briefs the application and characterizations of β‐CD based nanocomposites derivatives in molecular recognition.
