The programmed assembly of single DNA strands into bricks and ultimately micrometre-sized two-dimensional crystals with prescribed depths up to 80 nm is described. These crystals display intricate three-dimensional features including continuous or discontinuous cavities and channels with nanometre precision, and can pack DNA helices in parallel or perpendicularly to the plane of the crystals.
