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.

Optical imaging of bacterial infection in living animals is usually conducted with genetic reporters such as light-emitting enzymes or fluorescent proteins. However, there are many circumstances where genetic reporters are not applicable, and there is a need for exogenous synthetic probes that can selectively target bacteria. The focus of this study is a fluorescent imaging probe that is compos...
