A highly selective turn-on near-infrared fluorescent probe for hydrogen sulfide detection and imaging in living cells.

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.

Noninvasive optical imaging of staphylococcus aureus bacterial infection in living mice using a Bis-dipicolylamine-Zinc(II) affinity group conjugated to a near-infrared fluorophore.

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...
