a Overview of helical nanofiber-guided chiral assembly of gold NPs. b Models (left) and AFM images (right) of helical nanofibers. c CD spectra of hydrogel containing Au (I) ions after UV irradiation for reductive growth of gold NPs on the helical nanofibers. Reproduced with permission from [14]. d Schematic of the functionalization of AuNR@CTAB with MUTAB via ligand exchange method. e Cartoon representation of the TMV structure and the schematic presentation of the electrostatic interaction between TMV and AuNR+. f 3D reconstruction image with arrows pointing to the helical twist. g Experimental CD spectra showing stronger signals with gradually higher TMV concentration, along with the simulated CD spectrum calculated from the AuNR+ coordinates obtained from f.
