Abstract

The fieldo fc hiral plasmonics has received increasing attention in various areas of nanoscience due to the unprecedented light-matter interactions and promising optical applications. Chiral arrangemento fn anoparticles is one of the strategies employed for fabrication of chiraln anostructures. These arrays exhibit collective chirality,w here the chiroptical properties are governed by the geometricalp arameters with nanometer precision.I nt his regard, the self-assembly of biomolecules, such as peptides, DNA, and macromolecules, and their integration with plasmonic buildingb locks, can provide ar oute for the design and production of chiral plasmonic assemblies. In this Focus Review,w eh ighlight 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.

“…U nderstanding chiral nanostructures is of central importance in a broad range of scientific fields, including chiral recognition and separation of molecules in reactions 1 , handedness-dependent optical responses 2 , and mechanical function in chiral structures 3 . Recently, chiral structures combined with plasmonic materials have gained special attention owing to their unprecedented optical properties [4][5][6][7][8][9][10][11] . The unique characteristics of plasmonic materials that can maximize the light-matter interaction have opened up possibilities to utilize polarized light by rational design of plasmonic nanostructures [12][13][14][15][16] .…”

“…Chirality, a structural property prevalent in nature, refers to a geometrical orientation being non‐superimposable to each other. Especially in the field of plasmonics, strong chiral light‐matter interaction has been one of the fundamental needs with its wide potential application in chiral recognition sensing, optical metamaterials, enantioselective catalysis, and opto‐tele communication technologies . In this sense, relentless efforts have been dedicated to the construction of chiral plasmonic nanostructures using E‐beam lithography, direct laser writing, and macromolecular assembly .…”

[1][2][3][4][5][6][7][8][9] In this sense, relentless efforts have been dedicated to the construction of chiral plasmonic nanostructures using E-beam lithography, [10][11][12] direct laser writing, [13,14] and macromolecular assembly. [15][16][17][18][19][20] Despite sophisticated control of chiral nanostructures, state of the art technologies require complicated synthetic processes and have limitations on constructible morphologies.…”

Chirality‐Based Biosensors

“…Great progress has been made in the fabrication of discrete NP assemblies, identification of their properties, and their applications as chirality‐based biosensors. The basic assembly unit is usually an achiral NP that is made from a metal, a semiconductor, or an upconversion NP . Plasmonic NPs are important building blocks that induce circular dichroism (CD) peaks in their plasmonic bands.…”
