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 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.
在过去的几十年中,分子印迹聚合物(MIP)作为选择性合成受体已经出现,它们具有针对特定分析物/靶分子的选择性结合位点。MIP 是天然生物抗原-抗体系统的合成类似物。由于它们具有高稳定性、简单的合成程序和成本效益等优点,MIP 已被广泛用作各种分析物的检测和监测的受体/传感器。此外,将电化学传感器与 MIP 集成提供了一种很有前途的方法,并展示了比传统 MIP 更大的潜力。在这篇综述中,我们总结了基于 MIP 的电化学传感器的生产方法和技术,以及报道的 MIP 传感器在各种分析物中的应用。我们对使用 MIP 传感器实现的纳摩尔(pM/10 M)及更高纳摩尔浓度检测限(≥pM)的最新趋势进行了全面深入的分析。最后,我们讨论了面临的挑战,并提出了未来的展望和结论。
