All lined up : A method to assemble and align metallic nanowires relies on an aqueous suspension wetting and dewetting patterned substrates to direct the deposition of nanowires. Through designing substrate patterns with appropriate wettability, shape, and dimension, the assembly of nanowires in 100 μm square, 20 μm square, and 20 μm line features was demonstrated on the centimeter scale, as well as the alignment of nanowires in 2‐μm and 830‐nm hydrophilic stripes (see image).
