An efficient two-photon fluorescent probe for monitoring mitochondrial singlet oxygen in tissues during photodynamic therapy

Chem Commun (Camb). 2016 Oct 11;52(83):12330-12333. doi: 10.1039/c6cc05880a.

Abstract

A promising two-photon fluorescent probe MNAH for detecting 1O2 during the PDT process in mitochondria was proposed for the first time. MNAH was successfully applied for two-photon imaging of 1O2 in living cells and tissues during the PDT process with deep-tissue imaging depth. MNAH can be a powerful molecular tool for studying 1O2 generation in mitochondria during the PDT process.
