“…Such a low LOD was achieved due to the synergistic effect of enhanced recognition ability and affinity of imprinted cavities for NFZ owing to the bifunctional monomers, porous nature of ZIF, and improved electron conduction capability of MWCNTs. The standard addition method was employed for real samples (urine and water) analysis, indicating satisfactory recoveries [ 68 ].…”

Over the last decades, molecularly imprinted polymers (MIPs) have emerged as selective synthetic receptors that have a selective binding site for specific analytes/target molecules. MIPs are synthetic analogues to the natural biological antigen–antibody system. Owing to the advantages they exhibit, such as high stability, simple synthetic procedure, and cost-effectiveness, MIPs have been widely used as receptors/sensors for the detection and monitoring of a variety of analytes. Moreover, integrating electrochemical sensors with MIPs offers a promising approach and demonstrates greater potential over traditional MIPs. In this review, we have compiled the methods and techniques for the production of MIP-based electrochemical sensors along with the applications of reported MIP sensors for a variety of analytes. A comprehensive in-depth analysis of recent trends reported on picomolar (pM/10−12 M)) and beyond picomolar concentration LOD (≥pM) achieved using MIPs sensors is reported. Finally, we discuss the challenges faced and put forward future perspectives along with our conclusion.

“…Research has shown that using two different functional monomers can create multiple interactions between MIP cavities and template molecules, thus providing stronger selectivity and affinity. 17 Recently, cyclodextrin (CD) and its derivatives have emerged as promising functional monomers for MIP synthesis, with resulting MIP successfully applied for the selective extraction of target analytes. 18 CD refers to a class of cyclic oligosaccharides consisting of six, seven, and eight glucose units for α-, β-, and γ-CD, respectively.…”

“…However, in most MIP preparation methods, only a single functional monomer is employed and the single interaction force may sometimes be insufficient to achieve favorable recognition in a complex system. Research has shown that using two different functional monomers can create multiple interactions between MIP cavities and template molecules, thus providing stronger selectivity and affinity …”

Authenticating whole wheat foods poses a significant challenge for both the grain industry and consumers. Alkylresorcinols (ARs), serving as biomarkers of whole wheat, play a crucial role in assessing the authenticity of whole wheat foods. Herein, we introduce a novel molecularly imprinted electrochemical sensor with modifications involving a molecularly imprinted polymer (MIP) and MXene nanosheets, enabling highly sensitive and selective detection of ARs. Notably, we specifically chose 5heneicosylresorcinol (AR21), the predominant homologue in whole wheat, as the template molecule. α-Cyclodextrin and acrylamide served as dual functional monomers, establishing a robust multiple interaction between the MIP and AR21. As a result, the sensor exhibited a wide linear range of 0.005 to 100 μg•mL −1 and a low detection limit of 2.52 ng•mL −1 , demonstrating exceptional selectivity and stability. When applied to commercial whole wheat foods, the assay achieved satisfactory recoveries and accuracy, strongly validating the practicality and effectiveness of this analytical technique.

“…32,33 In general, molecularly imprinted electrochemical sensors do, however, have the disadvantages of low electron transfer efficiency and weakened electrical signal conversion, resulting in a relatively low sensitivity. 34,35 Consequently, modified materials with excellent electrical conductivity and large specific surface areas can enhance electrochemical performance.…”
