The integration of molecularly imprinted polymers (MIPs) with microfluidic systems has emerged as a powerful strategy for developing selective and sensitive analytical platforms. As "artificial receptors," MIPs offer robustness, reusability, and cost-effectiveness, while microfluidics enable precise fluid handling and miniaturized analysis. Together, they yield hybrid sensors capable of real-time detection. Recent advances in polymerization, nanoimprinting, and surface functionalization have tailored MIPs for seamless microfluidic integration. In parallel, innovations in soft lithography and 3D printing have expanded design possibilities for lab-on-chip architectures. Cutting-edge detection modalities, including electrochemical, optical, and mass-based transduction, have unlocked applications in biomedical diagnostics, environmental monitoring, and food safety. Examples include continuous biomarker monitoring, trace pollutant detection, and rapid food contaminant identification. Despite progress, challenges in reproducibility, large-scale fabrication, and commercialization remain. Addressing these through material innovations and scalable engineering will accelerate translation into point-ofcare testing, environmental protection, and global food security.
