Separately, chiral organic scaffolds (e.g., DNA, DNA origami and peptides) have also been used to coax achiral plasmonic nanocrystals (NCs) into chiral assemblies [36][37][38][39][40][41][42][43][44][45][46][47][48]. The tetragonal and

Even before any plasmonic nanocrystals with intrinsically chiral shapes were synthesized, Govorov et al. predicted the CD spectra of Au twisters with numerical simulations (Figure 6b) [115
