Preparation and molecular dynamics simulation of DNA bimodal materials. A Process used for the synthesis of DNNs and DNFs. The synthesized cross-linked network of DNA long chains exhibited two morphologies. One tended to form a DNA nanonetwork under the action of a topological enzyme, whereas the other tended to form a nanoflower structure under the action of ions and a topological enzyme. B Morphology of DNNs in the oxDNA simulation. In the simulation of oxDNA, the long-chain DNA exhibited three morphologies: DNN, a bimodal state, and DNF. C Dynamic potential energy. During the process of spontaneous DNA origami formation, the dynamic potential energy remained unchanged. D Dynamic hydrogen bond. During the process of spontaneous DNA origami formation, the dynamic hydrogen bond remained unchanged
