Abstract

Bisphenol A (BPA) is an endocrine-disrupting chemical widely used in the production of polycarbonate plastics and epoxy resins. The extensive use of BPA has increased concerns regarding its migration into food, beverages, and the environment, potentially causing adverse effects on human health. Therefore, the development of sensitive, selective, and rapid analytical methods for BPA detection is highly important. This mini-review discusses recent progress in molecularly imprinted polymer (MIP)-based electrochemical sensors for BPA detection. The review focuses on MIP synthesis methods, sensor platforms, analytical performance, and the incorporation of nanomaterials such as graphene, carbon nanotubes, and gold nanoparticles to improve sensor sensitivity and selectivity. Various recent studies demonstrated that MIP-based electrochemical sensors exhibit excellent analytical performance with low detection limits, wide linear ranges, rapid response, and successful application in real samples including water, milk, and packaged beverages. In addition, electropolymerization and nanomaterial modification have significantly enhanced electron transfer and sensor stability. Despite these advantages, several challenges remain, including long-term stability, reproducibility of MIP synthesis, template removal efficiency, and interference from complex sample matrices. Overall, MIP-based electrochemical sensors show great potential as practical and efficient tools for BPA monitoring in environmental and food safety applications.
