The transmission electron microscopy (TEM) image in Figure 3 b clearly shows that the gold nanowire is essentially composed of individual Au NPs transferred from the water surface. The TEM result in Figure 3 b also points to the occurrence of discontinuities within the nanowire due to the alkyl layer surrounding the Au NPs. To overcome the discontinuities in the nanowire and thus achieve effective electrical conductivity we further applied hightemperature annealing at around 350 C in an inert (argon) environment designed to remove all organic substances (both alkyl layer coating the Au NPs as well as surfactant molecules that make up the monolayer template) followed by a gold enhancement procedure.[11, 12] The enhancement process (also denoted as “gold seeding”) relied on soluble hydroquinone as the reducing …
