Silver ions (Ag+) are the most representative harmful ions found in polluted water and widely used in many industries; excessive ingestion of Ag⁺ in the human body may result in interaction with different metabolites in the human body and in aquatic microorganisms, leading to many diseases. Therefore, there is a great desire to develop good fluorescent probes for Ag⁺. Herein, a kind of mitochondrion-targeted fluorescent carbon dot was developed. These carbon dots exhibit 29.5% fluorescence quantum yield in water, good photostability and thermal stability. The as-fabricated carbon dots can quickly detect Ag⁺ in 100% water solution with good selectivity and anti-interference ability. Further, the carbon dots have been successfully applied to monitor Ag⁺ in living cells via the dual-channel method.

线粒体靶向荧光碳点的一步合成和银离子的荧光检测。

银离子（Ag +）是在污水中发现的最具代表性的有害离子，已广泛用于许多行业。过量摄入人体中的Ag ⁺可能导致与人体中不同代谢物和水生微生物的相互作用，从而导致许多疾病。因此，非常需要开发用于Ag ^+的良好荧光探针。在此，开发了一种针对线粒体的荧光碳点。这些碳点在水中的荧光量子产率为29.5％，具有良好的光稳定性和热稳定性。所制造的碳点可以快速检测100％水溶液中的Ag ⁺，具有良好的选择性和抗干扰能力。此外，碳点已成功应用于监测银通过双通道方法检测活细胞中的⁺。
