DNA deposits with submicrometer features can be prepared by micromolding in capillaries on a mica plate (see picture). Upon evaporation, surface properties of the DNA solution and the support come to the fore. The morphology of the DNA deposit can be controlled simply by adjusting the concentrations of the DNA solution and added salt.
