A simple and green strategy has been demonstrated for the synthesis of carbon dots (CDs) from mussels. The chemical structure and optical properties of mussels-derived CDs prepared at different reaction temperatures (140, 160, and 180 °C) were evaluated. The average size of synthesized fluorescent CDs decreased from 2.06 to 1.30 nm as reaction temperatures increased from 140 to 180 °C. The fluorescence quantum yield of CDs could reach up to 15.20%. The surface of CDs was rich in functional groups such as -OH, -NH2, and -COOH, providing CDs with good water solubility and biocompatibility. Furthermore, the mussel-derived CDs have been successfully applied in bio-imaging for onion endothelium cells, HepG2 cells, and zebrafish. In addition, CDs could be employed as a biosensor for riboflavin detection. Therefore, mussels are a promising carbon resource for preparing N-doped CDs for bio-imaging and monitoring riboflavin.

“…Until 2021, the fluorescence response of CDs towards herbicides [ 50 , 60 , 213 , 220 , 246 ] and fungicides [ 73 , 182 , 183 ] has also been explored. It is reported that with increasing concentrations of herbicides, i.e., atrazine [ 213 ], pretilachlor [ 60 ], glyphosate [ 50 ], and fungicide thiophanate methyl [ 183 ], this has resulted in an increase in PL emission intensity (turn-on).…”

“…It is reported that with increasing concentrations of herbicides, i.e., atrazine [ 213 ], pretilachlor [ 60 ], glyphosate [ 50 ], and fungicide thiophanate methyl [ 183 ], this has resulted in an increase in PL emission intensity (turn-on). This fluorescence ‘turn-on’ model was dynamic quenching, whereas, when the concentrations of trifluralin [ 220 ], pyrimethanil [ 182 ], and isoprothiolane [ 73 ] were increased, the fluorescence emission of CDs was found to decrease, leading to static quenching. Supchocksoonthorn et al (2021) suggested that the fluorescent quenching is closely related to the inner filter effect, due to the π-π interaction between the large aromatic core of the CDs and anilinopyrimidine unit of pyrimethanil and between their polar functional groups [ 182 ].…”

A Review on Carbon Dots: Synthesis, Characterization and Its Application in Optical Sensor for Environmental Monitoring

The development of carbon dots (CDs), either using green or chemical precursors, has inevitably led to their wide range application, from bioimaging to optoelectronic devices. The reported precursors and properties of these CDs have opened new opportunities for the future development of high-quality CDs and applications. Green precursors were classified into fruits, vegetables, flowers, leaves, seeds, stem, crop residues, fungi/bacteria species, and waste products, while the chemical precursors were classified into acid reagents and non-acid reagents. This paper quickly reviews ten years of the synthesis of CDs using green and chemical precursors. The application of CDs as sensing materials in optical sensor techniques for environmental monitoring, including the detection of heavy metal ions, phenol, pesticides, and nitroaromatic explosives, was also discussed in this review. This profound review will offer knowledge for the upcoming community of researchers interested in synthesizing high-quality CDs for various applications.
