The six nitrogen atoms are at the corners
of an octahedron around the Fe atom.

To create the nano cages, researchers start with a nanoscale cube or
octahedron of less expensive palladium, then deposit a few layers
of platinum atoms on top
of it.
When assembled into the 3D
octahedrons, each vertex
of the frame had a few
of these «sticky end» tethers available for binding with objects coated with complementary DNA strands.
«When nanoparticles coated with single strand tethers are mixed with the DNA origami
octahedrons, the «free» pieces
of DNA find one another so the bases can pair up according to the rules
of the DNA complementarity code.
The scientists then used these ropelike girders to form the frame
of three - dimensional
octahedrons, «stapling» the linear DNA chains together with hundreds
of short complementary DNA strands.
Scientists built
octahedrons using ropelike structures made
of bundles
of DNA double - helix molecules to form the frames (a).
The hovering guests include five regular, convex polyhedrons comprised
of identically sided, congruent faces: the tetrahedron, cube,
octahedron, dodecahedron and icosahedron.
It was perhaps his early experiences there that gave him, in the early 1960s, the confidence to hand over the paper and cardboard maquettes, that were the result
of his complex mathematical calculations — his studies
of the construction
of crystals, and
of how
octahedrons and tetrahedrons fitted together — to skilled crews
of metalworkers, whom he would direct to construct his mammoth sculptures.
«The outcome is a Regular Polyhedron — a «Truncated Cubic -
octahedron» — transformed into a inhabitable space; a self - standing volume with one
of his faces opened to the surroundings, and little windows on the sides and at the top that supply day light and optimal air circulation conditions.»
