Abstract
Sunset Yellow (SY) is an artificial colorant containing an azo group. The high stability and low cost of SY make it more preferable. Excessive consumption of SY, which is used to improve the appearance of foods, has harmful effects. The most important of these effects are cancer and hyperactivity disorder. Therefore, determination of SY in foods is extremely important for human health. In this method, L-cysteine coated copper nanoclusters (CuNCs) were used as a fluorescence probe. L-cysteine has been used as both a reducing and stabilizing agent. One-step green hydrothermal synthesis of CuNCs was made. L-cysteine-coated CuNCs have been characterized using several of methods. CuNCs quenching mechanism is static and inner filter effect (IFE). The linear range is 0.65-14 µg.ml− 1 at optimum conditions. LOD and LOQ values were calculated as 0.1–0.35 µg.ml− 1, respectively. The proposed method was used for the determination of SY in different type of powder drinks. The developed nanosensor is environmentally friendly, easy, fast, reproducible, and low cost.
