“…Fruit is a part of the plant that is also used as a carbon source of CDs for sensing Fe 3+ . CQDs were synthesized from jujubes using PET by Kim et al in 2018 with a sensing ability in the range 0–200 M. Other studies on carbon sources for sensing applied fruit such as Chionanthus retusus , [ 60 ] grape peel, [ 82 ] lycii fructus , [ 67 ] papaya, [ 69 ] Prunus cerasifera , [ 71 ] red lentils, [ 77 ] Seville orange, [ 73 ] watermelon juice, [ 76 ] and Phyllanthus acidus .

Carbon dots (CDs) are carbon nanoparticles with a size of less than 10 nm, and are synthesized from various sources; they have been of great interest to scientists worldwide due to their unique optical, electrical, and chemical properties. Sources of carbon are inexpensive and can be classified as a renewable natural resources. Many researchers use CDs because of their low toxicity, better water solubility, high biocompatibility, and stable photoluminescence. The simple methods for producing CDs are hydrothermal and use inexpensive equipment, have low energy consumption, simple manipulation, and one‐step preparation. Since the discovery of CDs, researchers have used them in various applications such as sensing, bioimaging, drug delivery, and catalysis. In this review, CDs synthesized from natural resources such as samples from herbs, roots, leaves, flowers, and fruit and some applications are described. This review provides a summary of carbon dots that is expected to provide further information for development of new CDs.

“…[17][18][19] It is generally considered that the modification of CDs not only enhances surface defects for fluorescence efficacy but also improves the reactive sites for specific binding. [20] Due to their easy preparation, low toxicity, good water solubility, and excellent optical properties, [21] CDs have been widely used in environmental monitoring, [22,23] biological imaging, [24,25] photocatalysis, [26,27] and food detection. [28,29] There are not many published studies concerning the using of carbon dots for the detection of folic acid in food samples even though they are promising candidate materials.…”

Glycidol‐modified polyethylenimine (PEI‐OH)‐capped carbon dots (PEI‐OH‐CDs) were prepared and applied for selectively and sensitively detecting folic acid in food samples. PEI‐OH‐CDs were firstly synthesized by a one‐pot hydrothermal method using PEI‐OH and citric acid as precursors, and the transmission electron microscopy characterization reveals that the PEI‐OH‐CDs were of spherical shape with diameters of 2–3 nm and well dispersed in solution. The PEI‐OH‐CDs have high fluorescence and exhibit ultrastrong stability against pH, ion strength, and UV light irradiation. In a wide pH range higher than pH 6, the fluorescence of PEI‐OH‐CDs can be effectively quenched by folic acid through static quenching process and inner filter effect but is not affected by many typical chemicals including cations, anions, amino acids, and vitamins. A good linear relationship was found between the F0/F and the concentration of folic acid in the range from 0.1 to 100 μM, and the detection limit of folic acid is 0.07 μM. The PEI‐OH‐CDs were successfully applied for sensitive determination of folic acid in orange juice, fresh pear, grape spinach, and celery samples at pH 7.2, which is helpful to the stability of folic acid and provides a new strategy for accuracy detection of folic acid in food samples.

“…Carbon dots (CDs), as a new type of the carbon family, are a smart choice to achieve this goal due to their high chemical stability, low toxicity, good photostability, and excellent biocompatibility. In addition, CDs have significant solubility in water due to their hydrophilic functional groups such as -COOH, -C=O, epoxy, and -OH, and are suitable for easy functionalization using different species [23][24][25].…”

Herein, for the first time, the wasted cockle shells were modified with nitrogen and sulfur-doped carbon dots after carbonization and used as a suitable bio-based sorbent for the extraction of two important antiemetic drugs named ondansetron and domperidone. The extraction and separation were performed based on vortex-assisted dispersive solid-phase microextraction and high-performance liquid chromatography, respectively. Various techniques such as Fourier-transform infrared, fluorescence, field emission scanning electron microscopy, thermogravimetric analysis, nitrogen adsorption-desorption analysis, X-ray powder diffraction, and energy-dispersive spectroscopy were used to characterize the chemical composition of prepared sorbent. After examining the factors affecting the extraction efficiency and access to the optimal points using the response surface methodology, the linearity was in the range of 5-350 μg/L with acceptable coefficients of determination (R 2 > 0.993). The limits of detection and quantification were in the range of 1.5-2.3 and 4.9-7.1 μg/L, respectively. In the end, the proposed method was applied for the quantitative determination of trace levels of target analytes from pharmaceutical tablets, serum, and urine samples. The recoveries were more than 95.2%, indicating the proposed method's excellent accuracy.
