摘要

鱼肉是人体营养的重要组成部分。然而，在其变质过程中产生的胺可能会影响人体健康。本研究合成了苯并噻唑-香豆素衍生物（MUS）。荧光探针对EtOH/H2O （3/7, v/v）溶液中的15种胺有明显的响应。装有MUS的指示标签不仅可以用肉眼识别大多数胺蒸气，还可以与智能手机结合，建立传感平台。通过智能手机上的应用程序提取标签的绿色(G)和蓝色(B)值，然后得到B/G（或G/B）值与测量的挥发性碱性氮（TVB-N）值之间的线性关系，可以实现对鱼类新鲜度的准确评价。同时，MUS生产的荧光油墨使用图章印刷在硅胶板上，产生蓝色印记，只有在365nm灯下才能看到。在设计好的纸质商标上印刷荧光油墨，可以获得具有防伪功能的商标。因此，MUS在食品安全检测、印刷、防伪技术等领域具有重要的应用潜力和广阔的发展前景。

Smartphone-assisted fluorescent probe to evaluate the salmon freshness

The meat of fish constitutes a significant component of human nutrition. However, the amines generated during its spoilage can potentially affect human health. In this study, the benzothiazole-coumarin derivative (MUS) has been synthesized. The fluorescent probe shows an obvious response to 15 amines in the EtOH/H₂O (3/7, v/v) solution. The indicator label loaded with MUS can not only identify most amine vapors with the naked eye but also build a sensing platform by combining it with a smartphone. The green (G) and blue (B) value of the label was extracted by using an app on the smartphone, and then the linear relation between the B/G (or G/B) value and the measured the Volatile Basic Nitrogen (TVB-N) value was obtained, which can realize the accurate evaluation of fish freshness. At the same time, the fluorescent ink manufactured by MUS is printed on a silica gel plate using a stamp, resulting in a blue imprint that can only be seen under a 365 nm lamp. Printing fluorescent ink on the designed paper-based trademark can obtain the trademark with an anti-counterfeiting function. Therefore, MUS exhibits significant application potential and broad development prospects in the domains of food safety inspection, printing, and anti-counterfeiting technology.
