Wang, Rui published the artcileFluorometric/electrochemical dual-channel sensors based on carbon quantum dots for the detection and information anti-counterfeiting, Synthetic Route of 90-64-2, the publication is Journal of Photochemistry and Photobiology, A: Chemistry (2022), 114118, database is CAplus.
Sensors used to detect Fe3+ and Cys are generally a single method. In this work, two methods of fluorescence and electrochem. are innovatively combined to detect Fe3+ and Cys, and the obtained Lod is basically the same. Carbon quantum dots (CQDs) with blue fluorescence were successfully prepared by hydrothermal methods using tryptophan (Trp) as carbon source, which can be used for fluorescence and electrochem. dual-channel probe quickly detecting iron ion (Fe3+) and cysteine (Cys). A series of studies have been carried out on its morphol., chem. structure, and optical properties through TEM, XRD, FT-IR, XPS, UV-vis absorption spectrum, and photoluminescence spectra. And the quantum yield of CQDs was up to 52.64%. It was also analyzed in the real sample, demonstrating the feasibility and reliability of detecting Fe3+ and Cys in the real sample. Furthermore, CQDs can also be used as fluorescent ink for information anti-counterfeiting due to their excellent fluorescent properties.
