A research group from Kobe University in Japan have proposed and tested a nano-antenna that uses the specific optical resonance of dielectric nanoparticles to form a near field of circularly polarized light. This technique bolsters the circularly polarized light-selective response of chiral molecules. The results of this study should provide applications in chirality analysis and asymmetric photochemical reactions for biomolecules, chemical substances, and pharmaceuticals.
