(a) Disordered deposition of a micellar nanowire on an unstructured surface, compared to (b) aligned nanowires after dewetting of microstructures (square pillars of $3.5\mathsf{\mu }\mathrm{m}$ in width, $2\mathsf{\mu }\mathrm{m}$ in gap, and $3\mathsf{\mu }\mathrm{m}$ in height) [29]. (c) Variation of the microstructure geometry yields different nanowire formations [48], also seen in (d), where a different flow direction angle of receding fluid in each picture additionally influenced the layout of resulting nanowires [47].
