“…Papaya peel was discarded and the flesh was chopped into small sections followed by drying at −54 • C for 24 h. They used 10 mL of 90% ethanol and deionized (DI) water as solvents. The mixtures were reacted at 200 • C for 5 h. Hoan et al prepared CDs from lemon juice (15 mL of extract and 10 mL of water) with the hydrothermal conditions of 240 • C temperature and 12 h reaction time [59]. Ahmadian et al synthesized N-CDs from grape, lemon, and turmeric extract [60].…”

“…The CDs derived from date kernel [63], groundnuts [54], and pineapple peel [64] exhibited absorbance peaks at 275, 279, and 280 nm, extending until the near-visible range associated with the aromatic C=C bonds of the π-π* transition. The UV-vis absorbance of CDs from lemon juice showed the absorption peak at 280 nm with a tail expanding to the visible region associated with the conjugated C=O bond transition [59]. CDs derived from scallion leaf showed a distinct peak at 281 nm which derives from C=C or C=N bonds of the π-π* transition [102].…”

“…They produced a QY of 42%, 13.45%, and 2.8%, respectively. Some plant part-derived CDs have a longer excitation wavelength at and above 400 nm, such as CDs from saffron (400 nm) [52], water hyacinth (400 nm) [86], white pepper (420 nm) [74], lemon juice (420 nm) [59], and aloe (441 nm) [48] with optimum emission wavelengths at 485, 486, 520/668, 540, and 503 nm, respectively. The FL QYs were 23.6%, 27%, 10.4%, 21%, and 10.37% for these CDs.…”

Carbon dots (CDs) are a new cluster of carbon atoms with particle size less than 10 nm. CDs also exhibit interesting fluorescence (FL) properties. CDs are attractive because of their fascinating characteristics including low toxicity, good water solubility, and tremendous biocompatibility. Recently, CDs have been investigated as biosensors for numerous target analytes. Meanwhile, the utilization of cheap and renewable natural resources not only fulfills the pressing requirement for the large-scale synthesis of CDs but also encourages the establishment of sustainable applications. The preparation of CDs using natural resources, i.e., plants, offers several advantages as it is inexpensive, eco-friendly, and highly available in the surroundings. Plant parts are readily available natural resources as the starting materials to produce CDs with different characteristics and attractive applications. Several review articles are now available covering the synthesis, properties, and applications of CDs. However, there is no specific and focused review literature discussing plant part-derived CDs for biosensing applications. To handle this gap, we provide a review of the progress of CDs derived from various plant parts with their synthesis methods, optical properties, and biosensing applications in the last five years. We highlight the synthesis methods and then give an overview of their optical properties and applications as biosensors for various biomolecules and molecules in biological samples. Finally, we discuss some future perspectives for plant part-derived CDs for better material development and applications.

For environmental protection, organic dyes and solvents of industrial wastewater must be eliminated. Here, a citric acid‐based carbon dots (CA‐CDs) crosslinked chitosan/microcrystalline cellulose (CS/MCC/CA‐CDs) sponge was synthesized to study its adsorption performance for methyl blue (MB) dye. The morphology of the sponge was a tangled fibre with a bundle formed by hydrogen bonds between CA‐CDs and the CS/MCC composite matrix. The abundant amount of tangled fibre bundle units can offer plentiful active adsorption sites to collect the dye molecules. The adsorption capacity of the CS/MCC/CA‐CDs sponge toward MB was 306.8 mg/g at pH 10 and a temperature of 298 K. In addition, the pseudo‐second‐order kinetic model was matched with the adsorption kinetic experimental data, and the adsorption isotherm data can be described by the Langmuir models. This study proposed that the CS/MCC/CA‐CDs sponge adsorbent creates tremendous potential application value in wastewater treatment due to its fast kinetics, high adsorption capacity, simple preparation, and eco‐friendly properties.

“…In particular, blue carbon quantum dots have been prepared in large quantities-and can even be produced in batches-of which the quantum yield is even higher than 75% [28][29][30]. Research on different photoluminescence and photocatalysis property of carbon quantum dots has also matured and stabilized [31][32][33][34][35][36][37][38][39]. Even the micromorphology control of carbon quantum dots has made great progress, such as triangular carbon quantum dots [40][41][42].…”

Tunable photoluminescent-functionalized carbon quantum dots CQDs@Ln (TFA)3 (Ln = Eu, Tb; TFA: trifluoroacetylacetone) were designed and synthesized by introducing lanthanide complexes into the modified CQDs surface through the carboxyl group. The as-prepared CQDs@Ln (TFA)3 emit strong blue–green light with the peak at 435 nm and simultaneously show the characteristic emission of Ln3+ under irradiation of 365 nm light in aqueous solution. Moreover, these functionalized CQDs exhibit excellent photoluminescence properties. In addition, a white luminescent solution CQDs@Eu/Tb (TFA)3 was obtained by adjusting the ratio of Eu3+/Tb3+ and the excitation wavelengths. Moreover, CQDs@Tb (TFA)3 can be utilized as a fluorescent probe for the sensitive and selective detection of MnO4− without interference from other ions in aqueous solution. These results provide the meaningful data for the multicomponent assembly and the photoluminescent-functionalized materials based on the modified CQDs and lanthanide, which can be expected to have potential application in photocatalytic or sensors.
