Abstract
We have described a turn-on near-infrared fluorescent probe Cy-NO(2) based on nitro group reduction for intracellular H(2)S detection. The probe employs cyanine dye as a fluorophore, and is equipped with a nitro group as a fluorescent modulator. It is readily employed for assessing intracellular H(2)S level changes, and confocal imaging is achieved successfully.
