Jean-Pierre Sauvage, Fraser Stoddart, and Bernard Feringa won the Nobel Prize in Chemistry for developing the world's smallest machines, such as a microscopic motor which is about 1 nanometer wide. Since this is much smaller than the diameter of a human cell (about 10 microns), one potential medical application could be sending a drone into your cells for repair jobs. (A nanometer is 10 meters, and a micron is 10 meters.)
The radio of the scale of this motor to a human cell is like the scale of your thumb to which of these objects?
