A ratiometric mitochondria-targeting two-photon fluorescent probe for imaging of nitric oxide in vivo†
Abstract
A two-photon ratiometric fluorescent probe (Mito-N) has been developed for monitoring mitochondrial nitric oxide (NO) in vivo. Mito-N exhibited excellent selectivity and sensitivity toward NO among various ROS/RNS. The successful two-photon imaging of mitochondrial NO proved that Mito-N is a powerful noninvasive imaging tool in living systems.
