Fancy a copper? A sensing system for copper(I) ions, based on the interplay between a “classical” chemosensor and a fluorescent silica nanoparticle, is presented (see scheme). The occurrence of properly designed energy transfer processes and the observed increase of the affinity of the nanosystem towards Cu+ improve sensor performance at low metal ion concentrations in living cells.
