Abstract

Chirality, the property of asymmetry, is of great importance in biological and physical phenomena. This prospective offers an overview of the emerging field of chiral bioinspired plasmonics and metamaterials, aiming to uncover nature's blueprint for engineering nanostructured materials. These materials possess unique chiral structures, resulting in fascinating optical properties and finding applications in sensing, photonics, and catalysis. The first part of the prospective focuses on the design and fabrication of chiral metamaterials that mimic intricate structures found in biological systems. By employing self-assembly and nanofabrication techniques, researchers have achieved remarkable control over the response to light, opening up new avenues for manipulating light and controlling polarization. Chiral metamaterials hold significant promise for sensing applications, as they can selectively interact with chiral molecules, allowing for highly sensitive detection and identification. The second part delves into the field of plasmonics nanostructures, which mediate enantioselective recognition through optical chirality enhancement. Plasmonic nanostructures, capable of confining and manipulating light at the nanoscale, offer a platform for amplifying and controlling chirality-related phenomena. Integrating plasmonic nanostructures with chiral molecules presents unprecedented opportunities for chiral sensing, enantioselective catalysis, and optoelectronic devices. By combining the principles of chiral bioinspired plasmonics and metamaterials, researchers are poised to unlock new frontiers in designing and engineering nanostructured materials with tailored chiroptical properties.
