Speech Title:Recent advances in nano-biosensors development for rapid detection of food allergy
Food allergy has been becoming a global challenge causing food safety and public health issues. The World Health Organization (WHO) and Food and Agriculture Organization (FAO) have reported that 6%-10% of population is suffering from food allergy worldwide. Food allergy could trigger different allergic reactions ranging from the mild symptoms to the severe types, and even can lead to death if no treatment is applied in time. Unfortunately, there are no practical approaches to cure food allergy. Thus, early detection and avoidance of exposure to food allergens are the top options recommended by doctors. However, traditional detection methods, including immunoassays, mass spectrometry, and nucleic acid analysis, are usually time-consuming and labor-intensive or require specialized technicians and expensive equipment. In recent years, the rapid development of nanomaterials provides an opportunity to design novel food allergy detecting technologies. This study summarized the application and mechanisms of various nano-biosensors, including optical biosensor, electrochemical biosensor, and surface-enhanced Raman scattering-based biosensor technology, in food allergens detection. Research progress of various allergen receptors including antibodies, aptamers, molecularly imprinted polymers and cells, based on nano-biosensors, was also discussed. This study prospected the future developments and challenges in the field, which provides references for the development of cheap, rapid, and effective detecting technologies for food allergens.
