HOW TO MAKE NANO-ORIGAMI

Polyhedra

If you want to make nanometer-scale machines, you have to find a way to build them. And that means making all kinds of shapes. But how?

Nanomaterials are built in computer chip factories, but so far those only work for shapes that can be laid down layer-by-layer. And manipulating DNA strands gets you self-replicating molecules, but not necessarily the kinds of shapes you need to make machines. Nature builds complex geometric structures at this scale all the time, for example the protein coats on viruses are shaped like dodecahedrons (12-sided polygons).
