Advances and Prospects of Chiral Plasmonic Nanomaterials in Emerging Applications

Chiral plasmonic nanostructures have attracted considerable attention due to their remarkable optical behaviors, which vary significantly across spatial dimensions. By integrating plasmonic effects with complementary functionalities, researchers are uncovering entirely new classes of chiroptical materials with capabilities beyond conventional systems. These materials hold immense promise in diverse domains such as biosensing, asymmetric catalysis, and medical technologies. Recent progress in tailoring structural geometries and fine-tuning optical responses has further expanded the application scope of intrinsically chiral plasmonic systems. A wide range of designs has already been fabricated, enabling scientists to probe novel physical effects and practical uses. In this context, the present review highlights the different architectures of chiral plasmonic nanomaterials, explores the mechanisms underlying chirality generation, and surveys their roles in enantioselective detection, catalytic transformations, and biomedical applications. Additionally, we address current obstacles in synthesis and utilization while outlining strategic approaches and future directions for advancing these multifunctional materials.
