samples were 93.40-106.0% with RSD <1.69%, indicating outstanding reliability of the newly developed LFIS platform for accurate detection of CBZ. In comparison with seven other common pesticides, CBZ produced significantly weakened and stable fluorescence, indicating good specificity and stability of the developed platform over 4 weeks. Compared with current analytical methods, the smartphone-assisted PEI@Eu-MOF-mAbs dual-modal LFIS platform exhibited advantages of simple construction, easy operation, rapid response, obvious visualization to the naked eye, and intelligent quantitative analysis, highlighting its broad application potential for rapid screening and accurate point-of-care detection of CBZ in a large number of foods and agricultural products.
