The article reviews the emerging field of chiral carbon dots (c-CDots), which exhibit chiral effects in optical, electric, and biological properties. c-CDots have gained significant attention from various research communities due to their potential applications in drug delivery, sensing, and catalysis. The review discusses the chiroptical properties and chirality origin in extinction circular dichroism (ECD) and circularly polarized luminescence (CPL) of c-CDots. It also summarizes the synthetic strategies of c-CDots, including one-pot synthesis, post-functionalization with chiral ligands, and assembly into chiral architectures using soft chiral templates. The chiral effects on the applications of c-CDots are elaborated, covering areas such as drug delivery, chemical or biosensing, and regulation of enzyme-like catalysis. Finally, the challenges associated with synthetic strategies, understanding the origin of chirality, and potential applications are discussed. The review aims to provide a comprehensive overview of the latest developments and future prospects of c-CDots.The article reviews the emerging field of chiral carbon dots (c-CDots), which exhibit chiral effects in optical, electric, and biological properties. c-CDots have gained significant attention from various research communities due to their potential applications in drug delivery, sensing, and catalysis.
