Abstract

All-Dielectric Metasurface for Biosensing Applications All-dielectric metasurfaces support high-Q resonances, and they are free from heating and thus analyte damaging suffered from plasmonic counterparts, but have relatively low sensitivities due to large energy confinement within the high-index materials. In article number 2400425, Guangyuan Li and Yunhui Liu propose a new type of all-dielectric metasurface supporting nonlocal quasi-bound states in the continuum formed from the destructive interference of Mie surface lattice resonances. The authors demonstrate the suitability of this metasurface for biosensing applications due to the significantly and homogeneously enhanced near fields over large volumes.
