Using rna structures in living cells as programmable sensors and controllers for cellular behavior, scientists can design and program molecules which perform a designed function, such as for catalytic circuits, triggered assembly, autonomous locomotion, and so on.

To power nanomachines, a molecular fuel must store energy in a stable form – stable until it’s released. Distributed molecular robots are herds of simple machines communicating with each other to accomplish collective tasks. Like ants, these robots can attach to each other to form chains or walk on top of one another to create collective superstructures. With the right insight and careful touch, DNA can Be programmed to assemble itself into incredibly complex nanoscale objects called ‘DNA origami’. Nature builds powerful computers, your brain being a prime example. Molecular self-assembly allows scientists to create electrical circuits by growing them. It’s hard to catch a molecule; they’re too fast and too small. So scientists get others to catch them by making molecules to catch molecules. Then they can be studied and programmed.
