Doxycycline (DOX) is extensively utilized as a broad-spectrum antibiotic in animals and aquaculture. However, excessive residues of DOX can endanger human health ecosystems, adversely affecting sustainable development. A novel ratiometric fluorescent probe was designed for specific monitoring based on boron- nitrogen-codoped carbon quantum dots encapsulated metal–organic frameworks coupled with molecularly imprinted polymers (B,N-CQDs/ZIF-8@MIP). In the existence DOX, blue fluorescence quenched owing to inner filter effect, while yellow-green enhanced due combination Zn2+. Benefiting from dual-signal strategy layer, exhibited wide linearity range (0.05–20 mg L–1), favorable detection limit (LOD) 14.21 ng mL–1, fast response time (5 min), exceptional selectivity. The validity verified by detecting lake water milk desirable recoveries (90.16–97.18%). Moreover, portable sensing device smartphone-integrated B,N-CQDs/ZIF-8@MIP achieve visual clear color change an LOD 44.98 mL–1. Therefore, sensor advantages portability, easy operation, sensitivity showed tremendous application prospects on-site food environmental safety.
