“…The correlation coefficient R 2 was 0.9967 with a detection limit of 33 nM (Figure 5b). Compared with other detection methods, [ 29,43–48 ] the NCDs exhibited an excellent linear range and the lowest detection limit (Table 1). Hence, the NCDs can be used as an effective fluorescence probe for the detection of bilirubin.…”

“…The fluorescence quantum yield of the NCDs was calculated to be 23.4%, using quinine sulfate as a standard, which was higher than the reported fluorescence quantum yield from natural sources. [ 29 ] UV radiation and a long storage time had little effect on the fluorescence intensity of the NCDs, indicating that the NCDs had good photostability (Figure S3).…”

“…Anjana et al [ 28 ] have reported an effective fluorescence probe for the detection of bilirubin using sulfur (S)‐ and nitrogen (N)‐doped CDs, which were synthesized using citric acid and l ‐cysteine by a microwave‐assisted method. Recently, Ottoor and coworkers [ 29 ] have synthesized CDs from sunflower seeds, which were used to determine bilirubin content with a limit of detection of 2.03 μM. These synthetic doped CDs showed a moderate quantum yield and a high detection limit.…”

Nitrogen-doped carbon dots (NCDs) with bright blue fluorescence were constructed by a hydrothermal method using sucrose and L-proline as raw materials. The NCDs were characterized by transmitted electron microscopy, X-ray diffraction, Fouriertransform infrared spectrometry, X-ray photoelectron spectroscopy, and ultravioletvisible absorption and fluorescence spectroscopy to investigate the morphology, elemental composition, and optical properties. The NCDs had good water solubility, high dispersibility with an average diameter of only 1.7 nm, and satisfactory optical properties with a fluorescence quantum yield of 23.4%. The NCDs were employed for the detection of bilirubin. A good linear response of the NCDs in the range 0.35-9.78 μM was obtained for bilirubin with a detection limit of 33 nM. The NCDs were also applied to the analysis of real samples, serum and urine, with a recovery of 95.34% to 104.66%. The low cytotoxicity and good biocompatibility of the NCDs were indicated by an MTT assay and cell imaging of HeLa cells. Compared with other detection systems, using NCDs for bilirubin detection was a facile and efficient method with good selectivity and sensitivity.

Green chemistry is currently attracting more and more attention due to its eco‐friendly, and green carbon dots (g‐CDs) are creating a research boom. The g‐CDs have huge application prospects in analysis and detection due to their excellent optical properties, high biocompatibility, and low toxicity compared to other fluorescent materials. Based on the study of g‐CDs, the optical properties, synthesis methods, surface modification methods, and sensing mechanisms of g‐CDs are outlined, and the application in analysis and detection of environmental, food, biomolecules, and other organic small molecules are reviewed. At the same time, the challenges faced by g‐CDs are outlined. This review provides valuable references for further research and wider application of g‐CDs.

“…They include fruit parts, such as seed extract [108], flesh [59], peel [61,71], juice [60], and fruit waste [62]. Alternatively, hemicellulose [109] or cellulose, combined with caffeic acid as a green reducing agent [67], or other plant parts, such as Gynostemma plant [54], red cabbage [64], palm-derived powder [110], green tea [63], mint [111], or turmeric [104] leaves, sunflower seeds [112], roasted chickpeas [68], wheat straw [66], soybean residues [113], and sandalwood powder [114]. Some of these carbon sources have been used with the prospect of recycling household kitchen waste, although in line of principle, the same concept could be applied to industrial waste.…”

The family of carbon nanostructures comprises several members, such as fullerenes, nano-onions, nanodots, nanodiamonds, nanohorns, nanotubes, and graphene-based materials. Their unique electronic properties have attracted great interest for their highly innovative potential in nanomedicine. However, their hydrophobic nature often requires organic solvents for their dispersibility and processing. In this review, we describe the green approaches that have been developed to produce and functionalize carbon nanomaterials for biomedical applications, with a special focus on the very latest reports.
