Query: Chiral plasmonics   We present a comprehensive overview of chirality and its optical
manifestation in plasmonic nanosystems and nanostructures. We discuss top-down
fabricated structures that range from solid metallic nanostructures to
groupings of metallic nanoparticles arranged in three dimensions. We also
present the large variety of bottom-up synthesized structures. Using DNA,
peptides, or other scaffolds, complex nanoparticle arrangements of up to
hundreds of individual nanoparticles have been realized. Beyond this static
picture, we also give an overview of recent demonstrations of active chiral
plasmonic systems, where the chiral optical response can be controlled by an
external stimulus. We discuss the prospect of using the unique properties of
complex chiral plasmonic systems for enantiomeric sensing schemes.
