Abstract

Abstract : 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.
