Sensors have been extensively used owing to multiple advantages, including exceptional sensing performance, user-friendly operation, fast response, high sensitivity and specificity, portability, and real-time analysis. In recent years, efforts in sensor realm have expanded promptly, and it has already presented a broad range of applications in the fields of medical, pharmaceutical and environmental applications, food safety, and homeland security. In particular, molecularly imprinted polymer based sensors have created a fascinating horizon for surface modification techniques by forming specific recognition cavities for template molecules in the polymeric matrix. This method ensures a broad range of versatility to imprint a variety of biomolecules with different size, three dimensional structure, physical and chemical features. In contrast to complex and time-consuming laboratory surface modification methods, molecular imprinting offers a rapid, sensitive, inexpensive, easy-to-use, and highly selective approaches for sensing, and especially for the applications of diagnosis, screening, and theranostics. Due to its physical and chemical robustness, high stability, low-cost, and reusability features, molecularly imprinted polymer based sensors have become very attractive modalities for such applications with a sensitivity of minute structural changes in the structure of biomolecules. This review aims at discussing the principle of molecular imprinting method, the integration of molecularly imprinted polymers with sensing tools, the recent advances and strategies in molecular imprinting methodologies, their applications in medical, and future outlook on this concept.

Developing dinotefuran (DNF) sensing probe is crucial for the monitoring of DNF residues A dual-emission ratiometric fluorescent probe of sulfur-doped carbon quantum dots (S-CQDs) and copper nanoclusters (CuNCs) hybrid (S-CQDs/CuNCs) were developed for sensitive and selective detection of DNF The fluorescent signals of CuNCs were quenched in the presence of DNF, while the fluorescent signals of S-CQDs enhanced after the addition of DNF The ratiometric fluorescent performance of as-developed probe was mainly based on the inner filter effect (IFE) between S-CQDs and CuNCs Interestingly, the aggregation of CuNCs occurred after the addition of DNF, reducing the IFE effect between S-CQDs and CuNCs, leading to the fluorescent intensity of S-CQDs recovered and CuNCs fluorescence decayed The ratiometric fluorescent performance of S-CQDs/CuNCs illustrated a good sensitivity and selectivity ranging from 10 μM and 500 μM, with a low detection limit of 704 μM Importantly, real samples investigations implied the good application potential of S-CQDs/CuNCs in DNF monitoring
