Using DNA origami, the team designed 2D triangle-shaped building blocks that snap together, edge to edge, like puzzle pieces. Then, using cryo-electron microscopy (cryoEM), the researchers confirmed ...

In a first step scientists form V-shaped building blocks using DNA-origami techniques. Determined by the opening angle a defined number of building blocks self-assemble into a gearwheel. In a third ...

but much like crafting paper origami, scientists are limited to the designs they can conceptualize. To overcome creative blocks, researchers in the Department of Mechanical Engineering at Carnegie ...
