Advancing Food Safety Through Integrated Detection Technologies: A Comprehensive Analysis of Nanotechnology, Biosensors, And Supply Chain Risk Mitigation

Abstract

Food safety has emerged as a multidimensional global challenge encompassing microbial contamination, chemical residues, adulteration, and systemic vulnerabilities within increasingly complex agri-food supply chains. This research article synthesizes contemporary advancements in detection technologies, with a particular emphasis on nanotechnology, biosensors, next-generation sequencing, and multisensor systems. Drawing exclusively on the provided literature, the study critically evaluates how emerging technologies enhance the detection, prevention, and control of foodborne pathogens, chemical contaminants, and fraudulent practices. The methodology involves an integrative analytical framework combining technological evaluation with supply chain risk analysis to identify systemic improvements in food safety governance. Results indicate that nanomaterial-based sensing platforms, including carbon dots and electrospun nanofibers, significantly improve detection sensitivity and speed, while next-generation sequencing offers transformative potential for pathogen surveillance. Additionally, multisensor systems such as electronic noses and tongues provide promising avenues for real-time spoilage monitoring. However, technological advancements alone are insufficient without addressing systemic vulnerabilities such as food fraud and supply chain inefficiencies. The discussion highlights limitations related to scalability, regulatory harmonization, and consumer acceptance, while proposing future directions involving integrated smart systems and AI-enabled monitoring. The study concludes that a holistic approach combining advanced detection technologies with robust supply chain management and policy frameworks is essential for ensuring food safety in a globalized food system.
