Abstract

Electrochemical molecularly imprinted polymer (MIP)-based sensors have gained substantial attention for their high selectivity, sensitivity, and cost-effectiveness in pharmaceutical and biomedical applications. These sensors utilize the concept of molecular recognition by designing polymer matrices imprinted with target molecules, enabling precise detection in complex matrices. This article explores recent advances in MIP-based electrochemical sensors, their fabrication techniques, and their applications in drug analysis, biomarker detection, and disease diagnosis. Challenges such as reproducibility and commercialization are also discussed, alongside future perspectives for integrating MIP sensors with advanced technologies like microfluidics and wearable devices.
