Self-assembly breakthrough offers new promise for microscopic materials by mimicking biology

It’s like microscopic Ikea furniture that can assemble itself.

The illustration shows how droplets with different DNA strands first combine into chains, which are then programmed to fold into specific geometries, analogous to protein folding. The carpet highlights one folding pathway of a hexamer chain folding into a polytetrahedron. The zoom shows how the formation of DNA double helices drives droplet-droplet binding.
