ABSTRACT:
Viruses pose significant risks to human health and food safety, challenges that are compounded by the limitations of current detection technologies. While biosensors have improved viral detection capabilities, many conventional methods still struggle with issues such as low sensitivity, poor specificity, and limited real-time monitoring. Nanotechnology offers promising solutions to these limitations by enabling the development of highly sensitive, accurate, and selective biosensors enhanced with nanomaterials. This review explores recent progress in nanotechnology-based biosensors, focusing on the use of graphene oxide, silica, carbon nanotubes, gold, silver, zinc oxide, and magnetic nanoparticles for detecting both human and foodborne viruses. A unique contribution of this review is its comprehensive, system-wide approach—examining viral threats throughout the entire food supply chain, from production to consumption. It covers key viruses affecting humans, livestock (e.g., avian influenza virus), and crops (e.g., maize chlorotic mottle virus), and critically evaluates the performance, limitations, and practical applications of various nanobiosensing technologies. Challenges such as the non-culturability of certain viruses, interference from complex food matrices, and the scalability of biosensor manufacturing are also discussed. Finally, the review outlines future directions including multiplexed detection and integration with artificial intelligence. Although many of these technologies are still in early stages, nanoparticle-based biosensors hold significant promise for transforming viral detection and strengthening the resilience of the global food system.
