虽然已经有许多关于四环素类（TC）的检测或降解的研究，但是关于将TC的检测和降解功能集成在一个纳米平台上的联合收割机的能力的报道很少。本论文采用一种简便的方法合成了柠檬酸和Eu 3+接枝的氨基粘土@Au纳米复合材料（AC@Au-Cit-Eu），该纳米复合材料在可见光下表现出了前所未有的光催化降解TC的效率。结果表明，AC@Au-Cit-Eu纳米传感器可实现水溶液和真实的牛奶样品中抗生素TC的快速目视检测。纳米传感器对TC的检测限为11.2 nM。更重要的是，用AC@Au-Cit-Eu制作的试纸还可以通过智能手机中的彩色扫描APP实现TC的实时检测。同时，实验结果也证明了AC@Au纳米平台具有良好的光催化性能，在40 min内对三氯甲烷的降解率达到93.33%，反应速率常数明显高于其他光催化剂。这种策略大大减少了从发现到处理抗生素残留物的漫长过程，并大大利用了纳米复合材料。
Although there have been many studies on the detection or degradation of tetracyclines (TCs), there are few reports about the ability to combine the detection and degradation functions of TCs integrated on one nano-platform. Herein we developed a facile strategy to synthesize citric acid and Eu3+grafted amionclay@Au nanocomposite (AC@Au-Cit-Eu) that exhibited remarkable effect on visual detection, while the original AC@Au nano-platform displayed unprecedented visible-light-driven photodegradation efficiency of TCs. The results show that the AC@Au-Cit-Eu nanosensor can achieve rapid visual inspection of antibiotic TC in aqueous solution and real milk samples. The detection limit of the nanosensor for TCs was 11.2 nM. More importantly, the test strip made with AC@Au-Cit-Eu can also realize the real-time detection of TC through the color scanning APP in the smartphone. Meanwhile, the results also proved that the AC@Au nano-platform had good photocatalytic performance with a 93.33% degradation rate in 40 min for TCs and the reaction rate constant was significantly higher than many other photocatalysts. This strategy greatly reduced the lengthy process from discovery to disposal of antibiotic residues and greatly utilizes nanocomposites.
