Abstract:
We report on the generation of a super- and homochiral field where linearly polarized incident light is twisted by plasmonic dimeric nanostructure within the gap. The asymmetry in exciting a molecule's chiral polarizability is enhanced, resulting in discriminatory nanocolorimetry. A chromaticity shift is used to discriminate the handedness of chiral molecules which is sensitive, faster, and self-referenced, and requires only a single scan as compared to existing methods.
