About this collection
Chiral Nanomaterials have gone from being largely anecdotal curiosities to sophisticated materials with distinctively strong polarization rotation that had become an enabler for the areas, such as biosensing, catalysis and displays. Chiral nanostructures also have enormous potential in emerging technologies related to biomedicine, optoelectronics, spintronics, and information technologies. The great progress in the last two decades on the synthesis of chiral nanocolloids, their assemblies, chiral porous materials, chiral clusters, chiral soft nanostructured materials, chiral composites, to name a few, have made possible the discovery of new physical phenomena such as those related to the enhanced light-matter interactions and tunable Cosserat-Cauchy mechanics. This special themed collection in Nanoscale, guest edited by Professor David Amabilino (ICMAB, Spain), Professor Jeanne Crassous (CNRS Institut des Sciences Chimiques de Rennes, France), Professor Pengfei Duan (NCNST, China) and Professor Nicholas Kotov (University of Michigan, USA) aims to provide a platform to showcase the latest progress and challenges in chiral nanomaterials. We hope you enjoy reading the articles published in the collection.
