Specular Reflections: Plasmonic Metaparticles on a Blackbody Create Vivid Reflective Colors for Naked-Eye Environmental and Clinical Biodetection (Adv. Mater. 4/2018)

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.
