A simple fluorescence method to quantitatively monitor malachite green (MG) was introduced based on the conformation switch effect of MG-aptamer (Apt) and the fluorochrome of SYBR Green I (SGI). SGI can embed in the stem-loop structure of Apt to produce fluorescence. However, the fluorescence will be quenched when MG is introduced because of the specific binding of Apt to MG. Under the optimal conditions, the fluorescence method displayed excellent linear relationship between the fluorescence quenching efficiencies and the MG concentrations ranging from 0.02 μmol L −1 to 1.0 μmol L −1 . The detection limit of the method was 0.67 μg kg −1 (3 α / κ , n = 9) which is lower than the limit (1 μg kg −1 ) specified in the national standard of China (GB/T 19857–2005) and the limit (2 μg kg −1 ) specified by the European Food Safety Authority (EFSA, 2016). Excellent recoveries between 87.1% and 106.9% tested by spiking standards were achieved with RSD less than 6.4%. The data were confirmed by the method of HPLC, and the results proved that the established fluorescence method could be used for the rapid detection of MG in fish with high accuracy and sensitivity.

“…The exploration of new carbon sources that possess abundant reserve, green, simple and high quality CDs has drawn tremendous attention in the area of kitchen waste, such as vegetables. Various green and non-green vegetables, such as celery leaves, sweet pepper, lemon grass, tomato, carrot, rose-heart radish, turmeric, cinnamon, red chili, black pepper, hongcaitai, cauliflower, kelp, tomato, crown daisy leaves, cabbage, cherry tomatoes, scallion leaves, and red beet, have been reported, as shown in Table 2 [ 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 ]. Both green and non-green vegetables have many properties and their own advantages.…”

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.

“…[ 4,18,19 ] Currently, it has been reported that CDs could be used as fluorescence sensors to detect TCs. [ 20–23 ] However, the reported CDs were mainly for the determination of total TC content in samples, and their ability to recognize single TCs (TC, CTC, and OTC) is poor. Therefore, it is very meaningful to develop new CDs to detect TCs.…”

The synthesis of N‐doped carbon dots for visual differentiating and detection of tetracyclines

N-doped carbon dots (N-CDs) were synthesized from L-glutamine and triethanolamine using a one-step hydrothermal method. The N-CDs emitting blue fluorescence had selective responses to tetracyclines (TCs) and could be used as a fluorescent probe to realize the quantitative detection and qualitative analysis of TCs. A method for the determination of TCs using the N-CDs in actual samples was successfully established. The recovery rate was maintained at 97.50-105.60%, and the relative standard deviation (RSD) was less than 3%. In addition, TCs can be visually distinguished using filter paper by the different fluorescence colours (light green, dark blue, and yellow-green) of the N-CDs/TCs system under ultraviolet light. This study provides a relatively simple method to detect and identify TCs.fluorescent probe, N-doped carbon dots, tetracyclines | INTRODUCTIONTetracyclines (TCs), mainly including tetracycline (TC), chlortetracycline (CTC), and oxytetracycline (OTC), are commonly used as a disease-preventive medicine and feed additive in animal husbandry and aquaculture. [1,2] However, the long-term abuse of TCs has caused extensive drug residues in the environment that may endanger human health. Many studies have shown that the excessive intake of TCs can
