Figure 2. DIC image patterns distinguish between 2D and 3D AuNS geometries.
Correlated SEM and DIC images of (a) 2D AuNS showing plain bright or dark DIC image patterns and (b) 3D AuNS showing lobed DIC image patterns. (c) Simulated DIC images and structure of a 2D AuNS. (d) Simulated DIC images and structure of a 3D AuNS.
