Figure 3: Electron microscopy images of Au nanostructures grown with the addition of 100 mM chloride (a) or 100 mM bromide (b-c). (a) and (b) comprise SEM images of template-freed Au nanostructures and (c) a TEM image of a microtomed Au NT. The reaction time was 21 h for the samples shown in (a) and (c) and 10 days for the sample shown in (b).
