“…5D, the change of fluorescence intensity is not obvious, indicating that it had good anti-interference ability. resonance energy transfer (FRET) [41,42]. Additionally, the Zeta potential of CuNCs increased to -2.68 mV after the addition of DCCNa, indicating the oxidation of copper on the surface of the CuNCs to Cu 2+ , resulting in a decrease in negative charge (Fig.…”

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.

“…The Stern-Volmer equation under different temperatures (25, 35, and 45 C) could also be used to confirm static quenching. As displayed in Figure 7D, the K SV value decreased as temperature increased from 25 to 45 C, exhibiting that the mechanism was indeed static quenching [49,50].…”

Tannic acid (TA), as a stabilizing agent, was successfully utilized to establish blue‐emitting copper nanoclusters (TA‐Cu NCs) on the basis of a facile chemical reduction preparation method. Characterization results proved successful synthesis of TA‐Cu NCs with uniform size and excellent stability. TA‐Cu NCs exhibited a blue emission wavelength at 431 nm when excited at 364 nm. Interestingly, the as‐prepared TA‐Cu NCs were selectively quenched by furazolidone based on static quenching. In addition, this analysis platform for furazolidone detection had an excellent linear range from 0.5 to 120 μM with a detection limit of 0.074 μM (S/N = 3). Furthermore, the accuracy of this sensing method was successfully confirmed by detecting furazolidone in bovine serum samples, indicating that TA‐Cu NCs had bright application prospects.

In view of the significance of nitrofurantoin, there is an urgent need for efficient analytical methods for accurate detection of nitrofurantoin. Considering their superior fluorescence performance and rarity of reports regarding nitrofurantoin detection by fluorescent silver nanoclusters (Ag NCs), Ag NCs with good stability and uniform size were synthesized through a simple method by protection of histidine (His) and reduction of ascorbic acid (AA). Based on the quenching by nitrofurantoin, Ag NCs were applied successfully in the detection of nitrofurantoin with high sensitivity. In the range of 0.5–150 μM, a linear relationship was found between ln(F0/F) and nitrofurantoin amounts. Static quenching and inner filter effect were proved to be the main quenching mechanisms. Significantly superior selectivity and satisfactory recovery results in bovine serum indicate that Ag NCs provide a better choice for nitrofurantoin detection.
