Forget 3D printing—DNA and water now build tiny machines that assemble themselves A new approach breaks down complicated designs into modular building blocks for easy assembly from the bottom up.

The building blocks are strands of DNA that fold into a mechanically robust eight-sided octahedral shape, which Gang refers to as a voxel, with connectors at each corner that link each voxel together.
