Carbon dots (CDs) have attracted considerable attention as a new type of fluorescent carbon nanomaterial because of their excellent optical properties, biocompatibility, and high electrical conductivity. Research on CDs has been conducted for nearly two decades and has focused on numerous precursors, various synthesis conditions and properties and applications of CDs. Biomass is critical in the green development of CDs because of its low cost, environmental friendliness, and sustainable properties. This review focuses on the advantages and applications of biomass-derived CDs. In addition, the challenges of photobleaching, toxicity, and stability of biomass-based CDs are discussed in detail. Lastly, the prospects and challenges of biomass-derived CDs are highlighted. [Display omitted] Biomass-derived carbon dots (CDs) have recently attracted a mounting interest as readily available, non-toxic, and tailorable carbon-based nanomaterials. However, how to tune the optoelectronic properties and broaden the application is still controversial. In this review, CDs from biomass and their detailed properties and applications are summarized. Eventually, the current problems and the expected development foregrounds of biomass-derived CDs are proposed.
