Abstract

In this work, we propose a pH-regulated and target-activated fluorescent nanoprobe for highly selective monitoring of lysosomal azoreductase under hypoxia in living cells. We expect it will offer a potentially rich opportunity to understand the physiological processes of lysosomes under hypoxic conditions.
