Abstract: Abstract DNA nanotechnology and especially the DNA origami method are primal tools to create precise nanoscale objects. For DNA origami, a long ssDNA scaffold strand is folded by a multitude of smaller staple strands into base-pair accurate shapes, allowing for precise modification and incorporation of guest molecules. However, DNA origami are limited in size, and thus is the area that can be controlled with nanoscale precision. Prior methods of creating larger assemblies were either costly or lacked structural control. Here, we incorporate two methods of modularity into one exemplary modular DNA origami (moDON). The modularity allows for the creation of over 50,000 diverse monomers and subsequently the assembly of a plethora of fully addressable designer superstructures while keeping the construction cost very low. The here-introduced methods for modularity in DNA origami design offer an efficient, cost-effective solution for constructing precisely organized, and fully addressable structures on a variety of scales.
