Light-emitting nanoparticles could provide a safer way to image living cells: Berkeley Lab scientists show how tiny, metal-rich particles can be excited with a low-power laser for deep-tissue imaging

A research team has demonstrated how light-emitting nanoparticles can be used to see deep in living tissue. Researchers hope they can be made to attach to specific components of cells to serve in an advanced imaging system that can pinpoint even single cancer cells.
