A surface-assisted fabrication scheme enables direct surface coverage control of functionalized DNA nanostructures on centimeter-scaled silica (SiO2) 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.
