Chiral nanomaterials: evolving rapidly from concepts to applications

Abstract

Chiral nanostructures is one of the most rapidly developing research fields encompassing chemistry, physics, and biology. The rise to academic prominence of chiral nanostructures was fueled by their giant optical activity and the fundamental structural parallels between biotic and abiotic structures with mirror asymmetry. Our introduction and the themed collection provide both a timely snapshot and comprehensive overview of concepts being developed by a diverse spectrum of scientists around the world working in in chiral nanostructures from metals, semiconductors and ceramics. Many fundamental discoveries in this area are expected that are likely to encompass multiscale chirality transfer, chiral surfaces, biological signaling, and circularly polarized emitters. Technological applications being pursued along the way of fundamental studies include biosensing, healthcare, chiral photonics, and sustainable catalysis.
