“…The prepared BCDs have a diameter distribution ranging from 2 to 5 nm. In addition to plants, waste can also be used as a carbon source to prepare BCDs by pyrolysis, such as litchi seeds, litchi exocarp, coffee grounds, waste frying oil, watermelon peel, peanut shell, peanut skin, and the like. Water‐soluble fluorescent BCDs were prepared by simple pyrolysis using litchi seeds as a carbon source (Figure c).…”

“…Under visible light, the obtained BCDs solution is a light‐yellow, clear liquid, while under radiation with 365 nm ultraviolet light, the as‐prepared BCDs give off strong blue luminescence. Peanut shells and peanut skin can also be used as carbon source to prepare BCDs by pyrolysis, but the two preparation methods are different, so the properties of BCDs obtained are also different. Water‐soluble fluorescent BCDs was prepared by using low‐cost peanut shell as carbon source through simple pyrolysis reaction (Figure d).…”

Water‐soluble fluorescent BCDs was prepared by using low‐cost peanut shell as carbon source through simple pyrolysis reaction (Figure d). The QY of these BCDs is approximately 9.91%, and they are well distributed and have a spherical structure, a diameter distribution ranging from 0.4 to 2.4 nm and an average diameter of 1.62 nm.…”

Carbon dots (CDs) have received much attention due to their superior properties including water solubility, low toxicity, biocompatibility, small size, fluorescence, and ease of modification. The use of a more environmentally friendly method to prepare high‐quality CDs is still an urgent question waiting for solve. The use of renewable, inexpensive, and green biomass resources not only meets the urgent need for large‐scale synthesis biomass CDs (BCDs), but also promotes the development of sustainable applications. In this article, we summarize the representative methods for synthesizing BCDs in green and simple ways using biomass as a carbon source, including hydrothermal carbonization, and microwave, pyrolysis. The prepared BCDs have a uniform particle size distribution and a relatively high throughput, which provide a method to scale up industrial production. Moreover, the integration of specific optical properties, that is, tunable photoluminescence and up‐photoluminescence, has led to remarkable use in bioimaging, sensing, and drug delivery. But the current review is not particularly comprehensive for BCDs. Therefore, we now provide a review focusing on the synthesis, properties, and recent advances in BCDs in biosensing, bioimaging, optoelectronics, and catalytic applications.

“…And some green synthetic approaches for the preparation of CDs have also been developed by using inexpensive renewable resources as precursors like honey [12], ginger [13], lychee seeds [14], and peanut shells [15]. However, most of these approaches suffer from either high reaction temperatures or long preparation times.…”

An approach for the synthesis of fluorescent organic nanoparticles (FONs) with a quantum yield of about 14% has been developed using polyethylenimine and sucrose. The FONs were prepared under mild reaction condition. The obtained FONs showed high water dispersibility, intense fluorescence, excitation-dependent emission feature, excellent nanoparticle stability, and high photostability. The cytotoxicity of the FONs was also evaluated using A549 cells, and the cell viability value was demonstrated greater than 90% even when the concentration was up to 120μgmL(-1), which proved excellent biocompatibility and made them promising for cell imaging.
