Abstract:
A series of 3D AuNR dimers and trimers were fabricated under the guidance of DNA origami. By tuning the size, number and spatial configuration of AuNRs, their structural and componential asymmetries were rationally designed. Circular dichroism measurements showed that the resultant plasmonic chiroptical activities of these nanorod assemblies can be precisely tailored.
