Foldable, organic and easily broken down: Why DNA is the material of choice for nanorobots

Doctors know that we need smarter medicines to target the bad guys only. One hope is that tiny robots on the scale of a billionth of a metre can come to the rescue, delivering drugs directly to rogue cancer cells. To make these nanorobots, researchers in Europe are turning to the basic building blocks of life – DNA. Today robots come in all shapes and sizes. One of the strongest industrial robots can lift cars weighing over two tons.
