Ordered DNA origami arrays have the potential to compartmentalize space into distinct periodic domains that can incorporate a variety of nanoscale objects. Herein, we used the cavities of a preassembled 2D DNA origami framework to incorporate square-shaped DNA origami structures (SQ-origamis). The framework was self-assembled on a lipid bilayer membrane from cross-shaped DNA origami structures (CR-origamis) and subsequently exposed to the SQ-origamis. High-speed AFM revealed the dynamic adsorption/desorption behavior of the SQ-origamis, which resulted in continuous changing of their arrangements in the framework. These dynamic SQ-origamis were trapped in the cavities by increasing the Mg2+ concentration or by introducing sticky-ended cohesions between extended staples, both from the SQ- and CR-origamis, which enabled the directed docking of the SQ-origamis. Our study offers a platform to create supramolecular structures or systems consisting of multiple DNA origami components.
