Nanoantennas, which are periodic arrays of metal or dielectric nanoparticles, creating an enhanced electric field within the lattice plane via surface lattice resonances (SLRs) when illuminated. Embedding these nanoantennas into a resin substrate enables their use as nanoantenna stickers that can be applied to various substrate surfaces. We investigated the chiroptical effects of moiré metasurfaces composed of stacked TiO2 grating nanoantenna stickers by evaluating circular dichroism (CD) spectra.
