Scanning electron microscopy (SEM) images of the resulting materials formed at flow-rate ratio of 1 and at concentration of: a) 0.0024M (TTF), 0.0006M (hydrogen tetrachloroaurate) and b) 0.0072M (TTF), 0.0018M (hydrogen tetrachloroaurate). Figure S2. Graph showing the correlation between average widths of the structures with their standard deviation and the flow-rate ratio of the synthesis. The averages are calculated from approximately 100 different wires chosen randomly and from different areas for each sample.
