摘要

Abstract

Carbon dots are luminescent carbonaceous nanoparticles that can be endowed with chiral properties

making them particularly interesting for biomedical applications due to their low cytotoxicity and facile synthesis. In recent years

synthetic efforts leading to chiral carbon dots with other attractive optical properties such as two-photon absorption and circularly polarized light emission have flourished. We start this review by introducing examples of molecular chirality and its origins and providing a summary of chiroptical spectroscopy used for its characterization. Then approaches used to induce chirality in nanomaterials are reviewed. In the main part of this review we focus on chiral carbon dots

introducing their fabrication techniques such as bottom-up and top-down chemical syntheses

their morphology

and optical/chiroptical properties. We then consider emerging applications of chiral carbon dots in sensing

bioimaging

and catalysis

and conclude this review with a summary and future challenges.
