Biomolecule‐Enabled Chiral Assembly of Plasmonic Nanostructures

Abstract The field of chiral plasmonics has received increasing attention in various areas of nanoscience due to the unprecedented light‐matter interactions and promising optical applications. Chiral arrangement of nanoparticles is one of the strategies employed for fabrication of chiral nanostructures. These arrays exhibit collective chirality, where the chiroptical properties are governed by the geometrical parameters with nanometer precision. In this regard, the self‐assembly of biomolecules, such as peptides, DNA, and macromolecules, and their integration with plasmonic building blocks, can provide a route for the design and production of chiral plasmonic assemblies. In this Focus Review, we highlight biomolecule‐assisted methods for the chiral assembly of plasmonic nanostructures with emphasis on of the types of biomolecules and the geometry of the resulting assemblies. We present an overview of recent achievements in chiral plasmonic assemblies and provide perspectives for future directions in the field of chiral plasmonics.
