In-situ nitrogen-doped carbon dots for fluorescence sensing of tetracycline antibiotic

Recent progress of carbon dot fluorescent probes for tetracycline detection

“…5a). 45 As shown in Fig. 5b, the fluorescent intensity of N-CDs declined gradually with the increased c TC and the linear relationship between ( F 0 − F )/ F 0 and c TC could be summed as the equation: ( F 0 − F )/ F 0 = 0.00279 c TC + 0.02, R 2 = 0.994 ranging from 0.5–60 μM (Fig.…”

“Click” Reaction-Mediated Silk Fibroin-Functionalized Thiol-Branched Graphene Oxide Quantum Dots for Smart Sensing of Tetracycline

“…Tetracycline (TC) is a common anti-inflammatory drug extensively used to treat bacterial infections in medicinal industries . It exhibits an effective inhibitory effect on the infections of Gram-positive and Gram-negative bacteria, spirochaetes, ultraviruses, and Rickettsia by preventing the growth of peptide chains and protein synthesis. , As a consequence, TC is frequently used as a veterinary drug for the treatment of infections in animals . Long-term usage, however, may result in residual TC in milk, endangering human health by causing problems including anaphylaxis, hepatotoxicity, yellow teeth, nausea, vomiting, liver and kidney damage, and a rise in bacterial resistance to TCs. ,− Although the antimicrobial effect of TC improved the feed efficiency, the excessive use of TC results in its accumulation in meat products and fish .…”
