Sticky-ended cohesion has historically been the driving force for DNA self-assembly and was employed for self-assembled crystals to avoid unpredictable packing; however, this limits the diversity of resulting architectures. Here, the authors employ composable DNA tiles to form complex 3D architectures using blunt-ended motifs with single duplex interfaces, leveraging the geometry of the tile and the terminal nucleobase identity to control self-assembly outcomes.
