摘要
We report a water-soluble AIEgen (TYDL) to be self-assembled into fluorescent organic nanoparticles (TYDLs) for specific sensing of SO2 in living hepatoma cells. It is demonstrated that the TYDLs were suitable for ratiometrically detecting endogenous and exogenous SO2 in mitochondria with good selectivity, low detection limit (75 nM) and excellent photostability (>30 min). These findings imply the great potential applications of TYDLs for the diagnosis of SO2-related diseases in cell biology.
