Based on 4-bromo-1,8-naphthalic anhydride, one novel ratiometric fluorescence H₂S-probe (IDNA) was designed and synthesized. Further studies indicate that IDNA can sensitively recognize H₂S (detection limit of 7 μmol/L) with good selectivity and anti-interference ability. In addition, IDNA has satisfactory photostability in HeLa cells, ability of mitochondrial co-localization, and can be utilized in fluorescence imaging of H₂S.

用于检测高光稳定性细胞内H ₂ S的线粒体靶向比例探针

基于4-溴-1,8-萘酐，设计合成了一种新型的比例荧光H ₂ S探针（IDNA）。进一步的研究表明，IDNA可以灵敏地识别H ₂ S（检测限为7μmol/ L），具有良好的选择性和抗干扰能力。此外，IDNA在HeLa细胞中具有令人满意的光稳定性，线粒体共定位能力，可用于H ₂ S的荧光成像。
