Emerging nanotechnology for detection of mycotoxins in food and feed

Abstract

The term mycotoxin was coined for toxic metabolites secreted by some fungi in food, food products and feed. The most prominent mycotoxins include aflatoxins (AFs), deoxynivalenol, zearalenone, ochratoxin, fumonisin and patulin. Among these some are proved to be strong carcinogenic agents such as AFs B1 while others are under suspicion to have carcinogenic effects. Ingestion of such mycotoxin-contaminated food and feed pose to a threat, mycotoxicoses. Various conventional techniques are available for the detection of mycotoxins, but unfortunately as a consequence of their constraint, the development of new and rapid techniques is the need of the hour. The use of nanotechnology for the development of nanobiosensors would be the alternative sensitive methods for the rapid detection of mycotoxins. Implementation of nanomaterials in the fabrication of nanobiosensors and their use for the detection of the mycotoxins in food and feed is the centre of interest of this review. We have inventoried nanomaterials applied for weaving nanobiosensors, which includes carbon nanotubes, nanowires, nanoparticles, quantum dots, nanorods and nanofibers. In addition, we have extensively reviewed available nanobiosensors specific for different mycotoxins, their advantages and challenges.
