Patents by Inventor Dongran Han

Dongran Han has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240150392
    Abstract: Novel compositions and methods for engineering wireframe architectures and scaffolds of increasing complexity by creating gridiron-like DNA structures (FIG. 1). A series of four-arm junctions are used as vertices within a network of double-helical DNA fragments. Deliberate distortion of the junctions from their most relaxed conformations ensures that a scaffold strand can traverse through individual vertices in multiple directions. DNA gridirons, ranging from two-dimensional arrays with reconfigurability to multilayer and three-dimensional structures and curved objects, can be assembled according the methods presented herein.
