Advancements, challenges, and future prospects of nanobiosensors in food packaging for allergen detection

Food allergies have become a growing public health concern worldwide, affecting a significant number of individuals. Accurate detection and management of allergens in food products are essential to prevent adverse reactions and ensure the safety of allergic individuals. The aim of the current review was to discuss the recent advancements, challenges, and future prospects of using nanobiosensors for allergen detection in food packaging. It covered various aspects, including different types of biosensors, recognition elements, signal transduction mechanisms, and fabrication techniques. Nanobiosensors offer high sensitivity and real-time response, making them suitable for integration into different packaging materials. Techniques like layer-by-layer assembly, electrospinning, and inkjet printing enable precise placement of nanobiosensors. The potential of nanofabrication techniques is highlighted for the development of highly sensitive and selective devices. Overall, nanobiosensors have the potential to revolutionize the food industry by improving food safety for individuals with allergies. It is necessary to tackle issues such as interference, stability, and regulatory concerns, while future prospects hold promise for enhancing food safety and quality through nanobiosensor applications. Also, by enabling more effective allergen detection and management, nanobiosensors have the potential to significantly improve food safety for individuals with allergies and enhance overall consumer confidence in the quality and integrity of packaged food products.
