“…For example, Kang et al [25] used N-acetyl-L-cysteine (NAC) as reducing agent and stabilizer to effectively synthesize CuNCs through sono-chemical method, and it could detect Ag + . Yu et al [26] synthesized OVA-CuNCs using egg albumin ovalbumin (OVA) and 2mercaptobenzimidazole as raw materials through one-pot method and it was used to detect RA sensitively. Zou et al [20] synthesized Trp-CuNCs using D-tryptophan as a ligand through a rapid microwave-assisted method, and it was used for the detection of tetracycline.…”

In this article, the water-soluble blue-light-emitting copper nanoclusters (CuNCs) were prepared by polyvinylpyrrolidone (PVP) and ascorbic acid as templating and reducing agents severally. Optimization of synthesis conditions of PVP-CuNCs were studied and analyzed. It had good specificity and exceptional sensitivity detection for sodium dichloroisocyanurate (DCCNa)/rosmarinic acid (RA), with a linear response range of 0.03–2.4/0.03–0.9 µM and corresponding LOD value of 10.77/8.98 nM. Moreover, the fluorescent reaction mechanisms of the PVP-CuNCs-DCCNa and PVP-CuNCs-DCCNa-RA systems were discussed, and the sensing probe could be effectively used for the determination of DCCNa and RA in genuine samples, whose results were acceptable.
