Carbon dots (CDs) with blue fluorescence were synthesized using indole-3-butyric acid and l-tryptophan using a one-step hydrothermal method. The CDs were further employed as a fluorescent sensor with high selectivity for colorimetric and ratiometric detection of tetracycline (TC) in water. The limit of detection (LOD) was found to be 0.33 μM for TC with R = 0.98387. Besides, the CDs could be applied in practical water samples and showed good recovery.
采用一步水热法，以吲哚 - 3 - 丁酸和L - 色氨酸合成了具有蓝色荧光的碳点。这些碳点进一步用作荧光传感器，对水中四环素（TC）进行比色和比率检测，具有高选择性。发现TC的检测限（LOD）为0.33μM，R = 0.98387。此外，这些碳点可应用于实际水样，并显示出良好的回收率。
