Self-assembled DNA nanostructures enable nanometre-precise patterning that can be used to create programmable molecular machines and arrays of functional materials. [] Key Method We illustrate this method, which we term ‘fractal assembly’, by producing DNA origami arrays with sizes of up to 0.5 square micrometres and with up to 8,704 pixels, allowing us to render images such as the Mona Lisa and a rooster. We find that self-assembly of the tiles into arrays is unaffected by changes in surface patterns on the…

Constructing Large 2D Lattices Out of DNA-Tiles

TLDR
This review first summarizes currently available DNA tile toolboxes and the basic principles of lattice formation and hierarchical self-assembly using DNA tiles, and focuses on the recent approaches that have shown great potential for the controlled immobilization and positioning of DNA nanostructures on different surfaces.

Triangular DNA Origami Tilings.

Reciprocal Control of Hierarchical DNA Origami-Nanoparticle Assemblies.

TLDR

Meta-DNA structures

TLDR
It is demonstrated that a six-helix bundle DNA origami nanostructure in the submicrometre scale ( meta-DNA) could be used as a magnified analogue of single-stranded DNA, and that two meta-DNAs that contain complementary ‘meta-base pairs’ can form double helices with programmed handedness and helical pitches.
