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. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Recommanded Product: 7447-41-8).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Recommanded Product: 7447-41-8
