Fig. 3. Structural characterisation of chiral metamolecules. (a) Transmission electron micrograph of the 2-layer sheet DNA origami structures. (b) and (c) X- and L-shaped left-handed chiral structures assembled using three varieties of nanorods, respectively. The concentration of AgNO3 used to synthesise the nanorods used for the structures is shown above the images. All scale bars: 100 nm.
