AND-Logic Gated Electrochemical Sensor for Separate Detection of Aflatoxin B1 and Ochratoxin A via Split-Activator CRISPR/Cas12a.
To address the frequent co-occurrence of aflatoxin B1 (AFB1) and ochratoxin A (OTA) in real food matrices, as well as the difficulty of achieving both high-specificity recognition and rapid quantification with existing detection methods, this study developed an AND logic-gated electrochemical sensor based on split-acti...
