A surface‐assisted fabrication scheme enables direct surface coverage control of functionalized DNA nanostructures on centimeter‐scaled silica (SiO 2 ) substrates from 0 to 100 % (see picture). Electrostatic interactions between the DNA structures and the surface lead to dramatic topological changes of the structures, thereby creating novel formations of the crystals.
