Ultrafine plasmonic nanoparticles have been identified for their Mie plasmonic resonance, though with radiation losses. In article number 1704442 , Mady Elbahri and co‐workers describe how the janusity of the plasmonic interference of excited plasmonic nanoparticles induces low‐loss specular radiation and vivid colors on a blackbody. Such fascinating features, plus the Brewster effect, lead to the realization of naked‐eye detection of diseased exosomes containing analytes, unattainable in the extinction Mie mode.
