Ag is abundant in nature and is employed in practically every aspect of life. Furthermore, Ag+ contamination poses a severe hazard to human and environmental health due to the extensive usage of Ag products. Traditional Ag+ detection techniques include drawbacks such as high operational costs, sophisticated operating units and instruments, and strong technical demands. The use of fluorescence copper nanoparticles in pollution detection has received a lot of attention in recent times. The development of copper nanoparticles and the detecting of Ag+ are the major topics of this research. Utilizing fluorescence copper nanoparticles produced utilizing glucose (Glc) as a reduction mediator like a fluorescent probe, and a simple approach for determining Ag+ in water was devised. Due to its appealing properties, including such dissolution rate, widespread availability, simplicity of synthesis process, and excellent biocompatibility, fluorescence copper nanoparticles (F-CuNPs) have sparked a lot of interest, and a lot of time and effort has gone into their synthesis and usage. The slightly elevated metallophilic Ag+ contact served as such sensing element, efficiently quenching the fluorescent of AuAg NCs. Moreover, these fluorescence nanoprobes could have been used to identify Ag+ in the atmosphere, implying that they might be used as practical, dual-functional, fast-responding, and label-free fluorescent sensors for health and environmental assessment. The experiment’s analytical methodology would be that silver ions could fast and efficiently extinguish the fluorescent of Glucose-CuNPs. In the Ag+ region at 100 mol/L–600 mol/L (R=0 9845), a strong linear relation was discovered; the color is progressively improved below the observable region and visually colorimetrical measurement. Furthermore, the Glucose-CuNP instrument only detected Ag+ and was unaffected by other metal ions, demonstrating that Glucose-CuNPs have strong sensitivity for Ag+ sensing. Glucose-CuNP, as a result, accomplishes the identification of substantial metal Ag+ ions, and it has promising future applicability in environmental monitoring.
