Abstract

Sunset Yellow (SY), which is an artificial azo dye, is preferable for its high stability and low cost. The determination of SY in foods is extremely important for human health because excessive consumption of SY has harmful effects, such as hyperactivity disorder and cancer. 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 and 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.

利用包覆 L-半胱氨酸的纳米铜簇开发一种新型纳米传感器，用于测定粉末饮料中的食用色素日落黄。

日落黄（SY）是一种人工偶氮染料，因其稳定性高、成本低而备受青睐。由于摄入过量的日落黄会对人体产生有害影响，如多动障碍和癌症，因此测定食品中的日落黄对人体健康极为重要。在该方法中，L-半胱氨酸包被的纳米铜簇（CuNCs）被用作荧光探针。L-半胱氨酸既可用作还原剂，也可用作稳定剂。一步绿色水热法合成了 CuNCs。使用多种方法对 L-半胱氨酸包覆的 CuNCs 进行了表征。CuNCs 的淬火机制是静态和内部过滤效应（IFE）。在最佳条件下，其线性范围为 0.65-14 μg.ml-1。计算得出的 LOD 和 LOQ 值分别为 0.1 和 0.35 μg.ml-1。该方法可用于测定不同类型粉末饮料中的 SY。所开发的纳米传感器具有环保、简便、快速、重现性好、成本低等优点。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
