Polymer-Driven Co-Assembly of Achiral and Chiral Nanoparticles into Plasmonic Nanoclusters with Quantitatively Modulated Optical Chirality.

ABSTRACT: Chiral plasmonic nanoassemblies demonstrate enhanced chiral optical activity through plasmonic mode coupling, holding transformative potential for applications in sensing, catalysis, and quantum-optical technologies. However, the mechanisms underlying this enhancement-particularly the roles of structural geometry, plasmonic coupling, and chiral field amplification-remain incompletely elucidated. A significant challenge persists in designing coupled nanoassemblies with precisely controlled nanostructures to systematically investigate chirality enhancement. Departing from conventional approaches that incorporate chiral molecules, we present the co-assembly of achiral and chiral plasmonic nanoparticles (NPs) into AB_n-type nanoclustersand the correlation between inherent plasmonic c
