Recent Advances in Electrochemical Sensors for Mycotoxin Detection in Food

Abstract Mycotoxins pose a grave global threat to human life and health by contaminating food and feed and cause enormous losses in healthcare and trading. Trace mycotoxin concentrations and diverse matrices in food make identification and measurement challenges, necessitating highly specific and sensitive detection methods. Electrochemical (EC) sensors are characterized by simple operation, outstanding sensitivity, low cost, and facile miniaturization and have become a promising strategy for addressing specificity and sensitivity in detection. Recent studies on EC sensors for mycotoxin detection for food safety are reviewed here. First, we summarize the fabrication of EC sensors and techniques with enhanced specificity and sensitivity. Then, we review state‐of‐the‐art EC sensors for detecting major mycotoxins. Challenges and opportunities for this technology are further discussed. Finally, in‐depth information is provided on using EC sensors to detect mycotoxins for food safety, as well as the development of EC sensors for academic study and practical application.
