“…While capillary aggregation was initially described as being detrimental to the processing of high‐resolution polymer features made by lithography,15 advances in the controlled patterning of nanostructures have shown that capillary interactions can be used as a versatile and scalable fabrication step. For example, the wetting and drying of vertically aligned carbon nanotubes (CNTs) has been used to increase their packing density,17–22 to form periodic superstructures,23–25 to reorient thin films into horizontal sheets and multidirectional circuits,26–30 and to fabricate intricate 3D microarchitectures 28. 31–35 Similar principles have been used to manipulate nanofilaments made out of Si,36–39 Au,40 ZnO,41 Cu,38 hydrogels,1, 42 epoxy,1, 16 PMMA,12, 43, 44 PET,45 cyclic olefin copolymers,12 polyurethane,1 PDMS,46 various photoresists,15, 47, 48 and even biological fibers 49…”
