a Molecular structures of liquid crystal matrix (OIM) and chiral dopants (dopS and dopR). b Schematic formation of left-handed (M-type) and right-handed (P-type) chiral nanomaterials. c SEM images showing M- and P-helices formed in pure liquid crystal matrix, dopR-doped liquid crystal and dopS-doped liquid crystal, respectively; P-helices and M-helices are colored in blue and red, respectively. d–f TEM images, 3D models, and corresponding CD spectra of chiral nanomaterials prepared using 4, 10, and 15 nm spherical gold nanoparticles, and 8 × 20 nm gold nanorods.
