Nanomaterial-based biosensors for agro-product safety

Agro-product safety is one of the most important topics in our daily lives, making it particularly critical to assure the quality of all consumed agro-products. Therefore, it is highly desirable to develop sensitive and stable methods to detect the contaminants in agro-products. Meanwhile, nanomaterials with outstanding properties have received widespread attention. A variety of nanomaterials have been incorporated into biosensors to realize highly sensitive, stable, and rapid detection of contaminants in agro-products, such as mycotoxins, pesticides, antibiotics, heavy metals, and microorganisms. During the past years, more potential nanomaterials with more variety of structures have been applied to develop new kinds of biosensors, and show ultra-higher sensitivity in the field of agro-product contaminant detection. This review summarizes the latest researches in the field of nanomaterial-based biosensors for agro-product contaminant detection in the past four years ( 2017-2020). Furthermore, the limitations analysis and research trends in this field are also provided. (C) 2021 Elsevier B.V. All rights reserved.
