A new paper by Laaya Sabri, Qinglan Huang, Jui-Nung Liu, and Brian T. Cunningham from the Nanosensors Group at the University of Illinois at Urbana-Champaign introduces a fundamentally new class of all-dielectric nanoantenna field-enhancement structures for biosensing applications that, due to destructive farfield interference of resonant modes, functions as a nonradiating “anapole” in the visible spectrum.
