Green Carbon Dots in Food Analysis

Abstract

Carbon dots (CDs), a promising class of fluorescent carbon nanomaterials, have gained prominence in recent years owing to their outstanding fluorescent properties, straightforward synthetic methods, favorable biocompatibility, and diverse detection applications. These qualities position them as potential replacements for traditional semi-quantum dots. This chapter focuses on the current advancements in CD development, specifically highlighting their fluorescent properties, synthetic methodologies, and applications in food safety. Various synthetic approaches and the characteristics of diverse CD synthesis methods are also discussed. Practical uses of CDs as fluorescent probes in the realm of food safety, with a particular focus on their usefulness in detecting metal ions/anions, pesticides, veterinary medications, bacteria, functional components, and prohibited additives are also explored.
