Reversible two-photon fluorescent probe for imaging of hypochlorous acid in live cells and in vivo.

Herein, we have developed a novel reversible two-photon fluorescent probe that is well suited for monitoring HOCl levels selectively and instantaneously. Results showed the reversible and instantaneous responses of the probe towards intracellular HOCl. Moreover, the probe was successfully applied to the imaging of the HOCl levels in zebrafish and mice via two-photon imaging.
