一种检测焦性没食子酸的比率荧光探针及制备方法和应用
摘要：
本发明公开了一种焦性没食子酸的比率荧光探针，通过酰胺键将红色的CdTe量子点和蓝色的碳量子点形成具有可视化的比率荧光探针。通过实验发现随着焦性没食子酸的加入量增加，荧光猝灭现象逐渐增强，在0.05‑2μM之间有良好的线性关系。实验结果表明，该方法具有简便、快速地检测实际水样中焦性没食子酸的能力。
摘要（英）：

The invention discloses a ratio fluorescence probe for detecting pyrogallic acid. The visual ratio fluorescence probe is formed by red CdTe quantum dots and blue carbon quantum dots through amido bonds. An experiment finds that a fluorescence quenching phenomenon is gradually enhanced along with the increase of the addition of the pyrogallic acid, and a good linear relationship exists when the linear range is 0.05-2 mu m. An experiment result indicates that a method has the capability of detecting the pyrogallic acid in a water sample simply, conveniently and rapidly.
