Controlling the extent of cation exchange reactions is a promising route for tuning the material composition and properties of nanostructures Here we demonstrate how measuring the conductivity of nanowircs during cation exchange can be used to monitor the transition from CdSe to Ag2Se, in situ In addition, by imaging the some wire mat region before and after complete canon exchange, we find that the shape and morphology of the nanowires are completely preserved
