Abstract:
Herein, we report the assembly of gold nanobipyramids (AuNBPs) into static and dynamic chiral plasmonic nanostructures via DNA origami. Compared with conventional chiral dimers of gold nanorods (AuNRs), AuNBP dimers exhibit more intriguing chiroptical responses, suggesting that they could be a superior alternative for constructing chiral plasmonic nanostructures for biosensing.
