Figure 4: SEM images of template-freed Au nanostructures grown in the presence of 100 mM thiocyanate. (a) Au structures yielded after a reaction time of 21 h. (b) Au NTs obtained after a deposition time of 4 days. (c) Magnified image of the Au surface film of the sample shown in (b), the arrow marks a nanowire stump.
