    Nanoparticles shine with customizable color

    Engineers at Harvard have demonstrated a new kind of tunable color filter that uses optical nanoantennas to obtain precise control of color output. The advance has the potential for application in televisions and biological imaging, and could even be used to create invisible security tags to mark currency.
