The emergence of nanoenzymes has catalyzed the robust advancement lateral flow immunoassay (LFIA) in recent years. Among them, multifunctional nanocomposite enzymes with core–shell architectures are considered preferable for promoting sensing ability due to their good biocompatibility, precise control over size, and surface properties etc. Herein, we developed a dual-channel ensured (DFLIA) platform utilizing magnetic, colorimetric, catalytic enzyme (Fe3O4@TCPP@Pd) [TCPP, Tetrakis (4-carboxyphenyl) porphyrin] ultrasensitive highly accurate rapid detection Escherichia coli O157:H7 (E. O157:H7). Fe3O4@TCPP@Pd-mAb exhibits superior performance compared traditional AuNPs, including enhanced sensitivity an extended linear range, benefiting from its high brightness signal, strong magnetic separation ability, peroxidase activity (Vmax = 2.32 μM S1–). Moreover, Fe3O4@TCPP@Pd-labeled mAb probe exhibited exceptional stability affinity toward E. (with constant approximately 1.723 × 109 M–1), indicating potential efficient capture pathogen. Impressively, Fe3O4@TCPP@Pd-DFLIA achieved pre- postcatalytic naked-eye sensitivities 255 cfu/mL 77 cfu/mL, respectively, representing 41-fold improvement conventional AuNP-based LFIA also possessed specificity reproducibility [relative standard deviation (RSD) < 10%]. Additionally, established DFLIA satisfactory recoveries detecting pork milk samples, further validating reliability this immunoassays demonstrating utilization bioassays clinical diagnostics.
