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.

“…Carbon dots (CDs), a new type of zero-dimensional carbon nanomaterials with an average size less than 10 nm, have drawn tremendous attention due to their excellent biocompatibility, outstanding thermal and photon stability, and stable nanoscale sizes. , Since the first discovery of the CDs, various raw materials have been employed as carbon sources to prepare the CDs, including molecular precursors (e.g., o -phenylenediamine, phloroglucinol, citric acid, and phenols), biomass precursors (e.g., cellulose, chitosan, chlorophyll, and leaves), and waste materials precursors (e.g., waste tea, waste paper, and cigarette butts). In contrast to other precursors, the biomass polymers, with excellent properties such as being nontoxic, environmentally friendly, abundant, renewable, and inexpensive, are considered as ideal carbon sources with the aim of promoting large-scale industrialization of the CDs.…”

“… 32 Similarly, Zhu et al synthesized CDs by solvothermal reaction of naphthalenediol and K 2 S 2 O 8 in ethanol, and showed that PL originates from organic fluorophores. 33 Therefore, formation of molecular fluorophores can be anticipated during bottom-up synthesis of CDs in organic solvents as well.…”
