“…The molecular recognition ability, molecular stability among biomaterials, and structural rigidity of DNA molecules make them appropriate for use in the design and construction of various nanometer-scale structures and arrays, which are central to the growing field of structural DNA nanotechnology. Consequently, DNA nanostructures with diverse, well-defined geometries, including one-dimensional (1D) nanotubes, periodic two-dimensional (2D) nanolattices, − finite-size 2D rings, , 2D/three-dimensional (3D) molecular canvases, − and 3D polyhedral structures, − have been proposed for use in multiple applications, e.g., structural scaffolds for aligning nanomaterials, computations implemented with logic algorithms, drug delivery via DNA containers, and physical devices/biochemical sensors constructed using nanomaterial-embedded DNA molecules. − The demands of increasing interdisciplinary research and specific applications require the development of multidimensional nanostructures made of simple but versatile DNA building blocks.…”
