Light up my life: Stable, bright, conjugated-polymer nanoparticles (CPNs) show promise for fluorescence imaging of live cells. The cell-permeable CPNs are synthesized by a simple solvent exchange, and accumulate exclusively in the cytosol (see picture) without any noticeable inhibition of cell viability.
