Sulfurdioxide (SO2) is a one of reactive sulfur species (RSS) that plays significant roles in many physiological processes. While abnormal levels of SO2 in mitochondria have been related to various diseases. Hence, developing suitable fluorescent probe for monitoring SO2 is significant in living organisms. In this research, we designed and synthesized a mitochondrial-target probe Mito-NPH featuring

developing an effective SO32−/HSO3− detection method is important. This study chose coumarin derivatives as fluorescent acceptors and pyridinium acrylonitrile structures as fluorescent donors to create a ratiometricfluorescentprobe CPA using the fluorescence resonance energy transfer (FRET) effect. The probe CPA exhibited a fluorescence transition from red to green under excitation at 405 nm with an interval
fluorescence and reactive oxygen species (ROS) generation abilities upon aggregation. However, it is difficult for AIE-PSs to simultaneously achieve long-wavelength excitation (>600 nm) and high singletoxygen quantum yield, which restricts their application in deep-tissue PDT. In this study, four novel AIE-PSs were developed by appropriate molecular engineering, and their absorption peaks shifted from 478
A water-soluble fluorescent organic nano-photosensitizer for the ratiometric detection of mitochondrial G-quadruplexes with photodynamic therapy potential
We report a water-soluble AIEgen (TPAL) that can self-assemble into fluorescent organic nanoparticles for the ratiometric detection of mitochondrial DNA (mtDNA) parallel G-quadruplexes (G4s) with high selectivity, a low detection limit and photodynamictherapy (PDT) potential.
