Abstract: Food allergy has become one of the prominent issues in the fields of food safety and public health. Since there is no effective treatment for food allergy, avoiding dietary exposure to (or intake of) food allergens based on label information should remain the best option for allergy sufferers. The development of sensitive, accurate and efficient allergen detection technologies is crucial for protecting consumers’ safety and rights. As a multidisciplinary detection technology, biosensors have the advantages of high specificity, quick response and easy operation. The rapid development of nanomaterials has advanced the development of highly sensitive and high-throughput biosensors for the visual detection of food allergens. In order to provide more references for further research and application of biosensors in food allergen detection, this paper summarizes the general situation of food allergen detection by biosensors, and analyzes the latest development of various biological recognition elements and biosensors based on different nanomaterials in the field of food allergen detection,
