Fig. 2: Transfer of chirality from amino acids to gold nanocrystals.

a Schematic illustration of cysteine enantiomer-mediated growth of Au nanocrystals in the presence of exfoliated MoS2 nanosheets; Mo and S atoms are shown as blue and green spheres, respectively. b–e SEM (b, d) and TEM (c, e) images of as-synthesized Au/MoS2 nanostructures derived from 1.6 μM L-Cys (b, c) and D-Cys (d, e), respectively. f TEM, HAADF, and EDX element scan results of L-Cys-endowed branched Au/MoS2 nanostructures. g-j Diverse-angle TEM scan (g, h) and corresponding TEM tomography images (i, j) for individual Au/MoS2 nanostructures synthesized in the presence of 1.6 μM L-Cys (g, i) or D-Cys (h, j), respectively. k Asymmetric morphological simulation of synthesized Au/MoS2 nanostructures based on TEM tomography images of nanostructures prepared with L-Cys (i) and D-Cys (j).
