Pollen-stigma biomimetic framework: a CuCo 2 O 4 nanozyme-based electrochemical aptasensor for ultrasensitive aflatoxin B1 detection

, with excellent reproducibility, stability, and selectivity. Recovery rates in real food samples range from 97.61% to 101.53%. This pollen-stigma biomimetic framework not only provides a highly sensitive platform for AFB1 detection but also establishes a new paradigm for designing high signal-to-noise ratio biosensors for complex matrices.
