The synergistic effect of multiple mycotoxins in cereals increases their toxicity. Therefore, the simultaneous detection is great importance. Exonuclease III (Exo III) assisted electrochemical aptasensor has been used for mycotoxin detection, but two not previously reported. By utilizing Exo strand displacement, this study developed an strategy aflatoxin B1 (AFB1) and ochratoxin A (OTA). This method demonstrates excellent AFB1 OTA within range 0.001-500 ng mL-1, with limits as low 0.229 pg mL-1 0.564 OTA. was successfully applied to analyze grain samples, sensor good specificity, stability repeatability. adapter provides food a fast, simple highly sensitive platform.
