Carbon dots have attracted much attention due to their high fluorescence intensity, easy modification, good stability, and biocompatibility. However, the realization of low‐cost mass production of high‐quality carbon dots still faces great challenges. Biomass is of non‐toxic and environmentally friendly organism, but a lot of biomass is treated as waste for burning and landfill at present, causing irreparable pollution to the environment. In fact, many biomass resources are ideal candidates for preparing carbon dots. This review focuses on carbon dots including carbon quantum dots (CQDs) and graphene quantum dots (GQDs) which using biomass as carbon source on the aspects of plants and their derivatives, animals and their derivatives and municipal waste. The characterization of the structure and composition of biomass carbon dots, the regulation of fluorescence color and the methods of improving quantum yield (QY) including heteroatom doping and surface modification are introduced in detail. Moreover, biomass carbon dots for detecting metal ions and non‐metal molecules and their quenching mechanism are emphatically introduced in addition to summarizing the luminescence mechanism, and some promising prospects and challenges in this uplifting field are discussed.

Carbon dots, the celebrated green material among the nanocarbon family, are blessed with several interesting features like biocompatibility, solubility, tunable luminescence, and so forth. Herein, carbon dots derived from Mint leaf extract (M-CDs) via a green method are exploited for versatile applications as a biosensor, reductant, and biomarker. M-CDs are applied for fluorimetric sensing of biologically relevant folic acid through quenching response originating from the inner filter effect, with a limit of detection of 280 nM. The carbon dots were highly selective toward folic acid in a collection of 16 biomolecules. The specificity of carbon dots toward folic acid is explained based on the interaction between the two. Along with sensing, herein, we project M-CDs as a green reducing agent by demonstrating the reduction of Fe(III) and noble metal nanoparticle synthesis from their salt solutions. The particles are found to be significantly non-cytotoxic, as evident from the MTT assay performed on primary H8 cells. The application of M-CDs in multicolor imaging is also illustrated using HeLa cells.

“…Carbonization is the most common method employed for the synthesis of CDs. This method is widely used obtaining CDs from carbon‐containing precursors like watermelon peel, [29] orange peel, [30] onion waste, [19b] banana juice, [31] strawberry juice, [32] different leaves, [33] grass, [34] etc. CDs possess photoluminescence properties while some of them produce luminescence after surface passivation or functionalization [35] .…”

Carbon has always found a spotlight in human life either in the form of graphite, diamonds, activated charcoal, carbon nanotubes, or carbon dots (CDs). Carbon quantum dots (CQDs) or CDs became the centre of attraction because of their potential applications in biomedical field such as bio‐imaging, drug nanocarriers, gene therapeutics, photosensitizing agents, theranostics and provides other multifunctional diagnostic platforms. There are numerous advantages of CDs due to their biocompatibility, reduced toxicity, water‐solubility, ease of scale‐up, and, most notably their fluorescence properties contrary to other carbon nanostructures. In last few years, significant efforts have been put by various research teams to synthesize and develop nanostructured materials possessing specific functional properties and characteristics. This work focus on the recent developments in the synthetic approaches applied for CDs using environment‐friendly sources. This review also highlights the mechanistic aspects, applications of CDs in biomedicine and a multi‐sensing platform along with challenges and future perspectives of this promising field. The authors believe that this review will help audible researchers to select a suitable environment‐friendly approach for the synthesis of CDs from green sources with required functions and properties. It will also guide researchers to develop a more convenient, efficient, and environment‐friendly method for the synthesis of new tunable carbon dots.
