Finite-size, fully addressable DNA tile lattices formed by hierarchical assembly procedures

Decorated tiles: Self-assembling DNA nanostructures can be used to form addressable, size-controlled nanoarrays with a variety of programmed patterns. Arrays of DNA cross-shaped tiles were decorated with pixels of individual protein molecules. The letters "D", "N", and "A" on self-assembled 4 x 4 arrays (<80-nm square, see picture) were prepared by a minimal-depth strategy. (Figure Presented). © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
