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 R² = 0.98387. Besides, the CDs could be applied in practical water samples and showed good recovery.

碳点基荧光探针的一步合成，用于四环素的比色和比例传感

使用吲哚-3-丁酸和L-色氨酸通过一步水热法合成具有蓝色荧光的碳点（CD）。CD还被用作具有高选择性的荧光传感器，用于比色和比率检测水中的四环素（TC）。发现TC的检出限（LOD）为0.33μM ，R ² = 0.98387。此外，该CD还可用于实际水样中，并显示出良好的回收率。
