Material Voxels Platform Assembly (IMAGE) DOE/Brookhaven National Laboratory Caption Schematic of the platform for assembling 3-D lattices from inorganic and organic nano-objects with DNA frames shaped as a tetrahedron (top row), octahedron (middle row), and cube (bottom row). The frame valence is determined by the vertices and corresponds to the number of connections (bonds) and how these connections are organized relative to one another. For example, the tetrahedral frame has a valence of four. The resulting 3-D lattices are based on the shape of the DNA frame--tetrahedral frames assemble into diamond structures, octahedral into simple cubic, and cubic into body-centered cubic--regardless of which nano-object (if any) is inside the frame.
