Chiral plasmonic nanostructures: Twisted by DNA

Abstract

Noble-metal nanoparticles occupy the top drawer in the toolbox of scientists working with optical materials. These nanoparticles conne light in extremely small volumes, and their individual scattering properties can be designed virtually at will by shaping and arranging them carefully. When their behaviour is considered collectively, the nanoparticles can also be used as building blocks (meta-atoms or metamolecules) for metamaterials engineered materials

with eective homogeneous properties.
