Research progress on portable electrochemical sensors for detection of mycotoxins in food and environmental samples.

This review comprehensively discusses the performance of various electrochemical sensors using different detection recognition methods, based on nanomaterials, MIPs, aptamer, etc. The portable electrochemical sensors using smartphone, USB and disk are summarized in detail. The future research direction and challenges of using portable devices for the detection of mycotoxins are highlighted. [Display omitted] • Recent progress in electrochemical sensors is summarized for various mycotoxins detection in food. • The main electrochemical recognition methods for mycotoxins detection are discussed. • On-site portable electrochemical devices are reviewed. • Future research trends and perspectives on portable electrochemical sensors are presented. The mycotoxins commonly found in food may pose a significant threat to human health. Therefore, the development of portable electrochemical sensing chip methods is very important. In addition, due to the need to study various pollutants when conducting food analysis, which involves multiple and complex fields, the use of disposable portable sensing chips can improve detection efficiency. In this review, we have summarized the significant work on electrochemical sensors for mycotoxins detection in food samples. Although earlier reviews have covered this topic, the mechanisms and portable use of toxin detection have not yet been addressed. This paper's novelty is that it has reviewed recent advances in various electrochemical sensors and portable applications, for mycotoxins detection. This provides a new perspective on future trends in the development of portable electrochemical sensors. [ABSTRACT FROM AUTHOR]
