Wrinkle‐Assisted Capillary Bridging for the Directed Assembly of Single‐Level DNA Nanowire Arrays (Adv. Mater. Interfaces 6/2022)

Assembly of DNA Nanowire Arrays In article number 2102243, So Nagashima, Myoung-Woon Moon, and co-workers introduce a bottom-up method for readily assembling DNA molecules into periodically aligned 2-nm-thin nanowires. Anisotropically superhydrophilic wrinkles are used to develop capillary bridges of DNA solution that recede unidirectionally on a hydrophobic flat surface. The molecules in each capillary bridge are then evaporatively assembled into a nanowire. The inter-nanowire separation can be tuned by controlling the wrinkle dimensions.
