“…On the other hand, excessive use of veterinary drugs, antibiotics and pesticides in poultries and agricultural activities poses a serious threat to the animal bodies, human health and environment. Antibiotic residues such as tetracycline (Jayaweera et al, 2019), (Guo et al, 2020) and amoxicillin have been detected using C-Dots-based composite sensor through quenching of fluorescence (Guo et al, 2020) or enhancement and inner filter effect (Jayaweera et al, 2019). Traces of estrogen drugs that were used in animals, birds for fast growth can also be detected by C-Dots-based sensor very effectively (Zhao et al, 2018).…”

Carbon-Dots (C-Dots) have drawn much attention in recent years owing to their remarkable properties such as high biocompatibility, low toxicity, nano-scale size, and ease of modification with good tuneable photoluminescence performance. These unique properties have led C-Dots to become a promising platform for bioimaging, metal ion sensing and an antibacterial agent. C-Dots can be prepared using the top-down and bottom-up approaches, in which the latter method is commonly used for large scale and low-cost synthesis. C-Dots can be synthesized using sustainable raw materials or green biomass since it is environmentally friendly, in-expensive and most importantly, promotes the minimization of waste production. However, using biomass waste to produce high-quality C-Dots is still a matter of concern waiting for resolution, and this will be the main focus of this review. Fundamental understanding of C-Dots such as structure analysis, physical and chemical properties of C-Dots, various synthesis methodology and type of raw materials used are also discussed and correlated comprehensively. Additionally, factors affecting the bandgap of the C-Dots and the strategies to overcome these shortcomings are also covered. Moreover, formation mechanism of C-Dots focusing on the hydrothermal method, option and challenges to scale up the C-Dots production are explored. It is expected that the great potential of producing C-Dots from agricultural waste a key benefit in view of their versatility in a wide range of applications.

“…In the presence of tetracycline, fluorescence quenching of the NCDs occurs due to IFE. Recently, Guo et al have reported the detection of tetracycline using fluorescent CQDs obtained by the thermal cracking of crab shell waste [ 50 ]. With an average size of 10 nm and 30% fluorescent quantum yield, the highly stable CQDs could detect tetracycline with a LOD 5 μg L −1 .…”

“…The UV‐vis spectra in Figure S5c showed that no new absorption peaks generated with the addition of Tc, implying that no new complexes are formed. The absorption spectrum of Tc overlaps with the excitation spectrum of CDs, verifying the mechanism of the internal filtering effect (IFE) [31] …”

Bioinspired carbon dots (CDs) with excellent biocompatibility were prepared from egg white as precursors through a simple hydrothermal method at 200 °C for 4 hours. The obtained CDs exhibited bright blue fluorescence, excellent optical stability, and sensitive response to tetracycline. Under the optimized synthetic conditions, the fluorescence quantum yield is 17.6 %. The fluorescence intensity of CDs at 440 nm could be quenched linearly with the addition of tetracycline in the range of 0.1–200 μmol L−1 due to the internal filtering effect. The proposed detection platform has been applied in the determination of tetracycline in milk samples with good results. The limit of detection is 32.3 nmol L−1, and the spiked recoveries are in the range of 93–103 %. Additionally, the CDs could also be applied to cell imaging, implying good biocompatibility and low toxicity. As a type of green and effective multi‐functional fluorescence materials, the CDs have potential applications in biochemical sensing and biomedical imaging.
