A highly sensitive ratiometric fluorescent probe for detecting HSO < sub > 3 < /sub > < sup > - < /sup > /SO < sub > 3 < /sub > < sup > 2- < /sup > and viscosity change based on FRET/TICT mechanism
We reported a unique ratiometric probe QQD for detecting HSO3-/SO32- and viscosity based on the quinolinium skeleton. In addition to detecting HSO3-/SO32- and viscosity change in actual water and food samples, QQD could also monitor the variations of HSO3-/SO32- and viscosity in cells, which provided an experimental basis for further exploration of the role of SO2 derivatives and viscosity in biological systems.PMID:38677842 | DOI:10.1016/j.aca.2024.342588
