If you want to print something a few inches tall, extruded plastic is a good medium. But when you need something at the nanometer scale, DNA is a better bet — but who has the time to design and ...

The ancient art of origami is well known for transforming sheets of paper and other foldable materials into complex 3D shapes. But now, chemical engineers have extended the centuries-old practice to ...

‘Bottom-up fabrication’, which exploits the intrinsic properties of atoms and molecules to direct their self-organization, is widely used to make relatively simple nanostructures. A key goal for this ...

The art of origami usually requires dextrous fingers to turn a flat sheet into an intricate 3D shape. Now it’s got considerably easier, thanks to a material that can fold up on its own. Each foil was ...
