A sustainable method for the fabrication of metallic surfaces with flower‐like fractal morphology was developed by using a three‐dimensional supramolecular assembly as a template. Modifying Au nanoflakes with self‐assembled monolayers or polymers allows the surface wettability to be adjusted from superhydrophobic to superhydrophilic (see figure). Furthermore, Au nanoflakes present excellent substrates for surface‐enhanced Raman spectroscopy (SERS).
