When assembling a jigsaw puzzle, just shaking up the box and dumping the pieces in a pile probably isn’t the best strategy. The pieces won’t fit themselves together by chance. But in the nanoworld, this approach could prove surprisingly fruitful.

It might take the fun out of doing the puzzle, but scientists are now figuring out how to make the pieces move, on their own, into the desired positions for creating new materials. In this case, the puzzle pieces are nanoparticles, tiny collections o...
