Strand displacement is commonly used in DNA nanotechnology to program dynamic interactions between individual DNA strands. Here, the authors describe a tile displacement principle that is similar in concept but occurs on a larger structural level: the displacement reactions take place between DNA origami tiles, allowing reconfiguration of entire systems of interacting DNA structures.
