Advancements in Circularly Polarized Light and Chiral Mixture Sensing
Originally Published 2 years ago — by Phys.org
Researchers from Kobe University have developed a nano-antenna that utilizes dielectric nanoparticles to create a near field of circularly polarized light. This technique enhances the circularly polarized light-selective response of chiral molecules, which has applications in chirality analysis and asymmetric photochemical reactions for biomolecules, chemical substances, and pharmaceuticals. The nano-antenna preserves the helicity of incident circularly polarized light, resulting in improved circular dichroism and increased efficiency in light-molecule interactions. The developed nanoparticle solution also has potential for controlling light polarization.
