CdSe/ZnS quantum dot–Cytochrome cbioconjugates for selective intracellular O2˙ sensing

Author affiliations

Abstract

We demonstrate that the coupling system of negatively capped CdSe/ZnS QDs with an oxidized Cytochrome c (Cyt c) is capable of the fluorescent imaging of a superoxide radical (O2˙) with high sensitivity and specificity in living cells, without interference from other Reactive Oxygen Species (ROS) or relevant intracellular components.
