Chiral Materials: Chiral Surface Lattice Resonances (Adv. Mater. 22/2020)

Optical activity of surface lattice resonances is demonstrated by Nicolas Vogel and co-workers in article number 2001330. The controlled arrangement of chiral crescent-shaped nanoantennae allows a selective response of the surface lattice resonances to the handedness of incident circularly polarized light. Modified colloidal lithtography enables the fabrication of cm2-scale substrates using a self-assembled poly(N-isopropylacrylamide)–silica core–shell system as particle masks.
