Carbon dots-nanosensors: Advancement in food traceability for a sustainable environmental development

Abstract

The increasing complexity of global food networks and the possible hazards of fraud, foodborne diseases, and environmental damage highlight the need for strong food traceability systems. Nanoscale carbonaceous materials known as ‘carbon dots’ (CDs), have attracted interest due to their special optical qualities, biocompatibility, and capacity for surface functionalization. Due to these characteristics, Carbon Dots are perfect candidates for the creation of nanosensors that can track and identify indications at every stage of the manufacturing and distribution of food. Innovative solutions are required since conventional systems frequently fail to provide comprehensive and real-time information throughout the food supply chain. There are many different uses for Carbon Dots-based nanosensors in food traceability applications. These nanosensors can be designed to track the origins of food items, detect viruses, identify counterfeit goods, and monitor storage conditions. They are a vital tool for guaranteeing the security, authenticity, and quality of the food supply because of their great sensitivity, selectivity, and quick reaction. The overall objective of sustainable development is in line with the ecologically friendly characteristics of Carbon Dots. Various types of Carbon Dots and their working mechanism has been described in this review.
