Cell imaging Hemicyanine Mitochondria Pyrido[1,2-a]benzimidazole Water

摘要

A mitochondria-targeted ratiometric fluorescent probe based on hemicyanine and pyrido[1,2-a]benzimidazole was presented. It shows high sensitivity and selectivity toward SO 2 in pure water. The limit of detection was as low as 26.7 nM, which is superior to most reported probes. Most importantly, the probe was successfully used for fluorescence imaging of endogenous bisulfite in mitochondria in Glioma cells.
