What are molecular robots?
The material we use is a molecule called “DNA.”
DNA is found in every single cell of living organisms,
and it looks like a very thin thread.
Human DNA is about 2 meters long, yet its diameter is one millionth of that—
only 2 nanometers—about 1/50,000 the thickness of a human hair.
A “robot” made from such DNA is even smaller than a cell,
so it cannot be seen with an ordinary microscope.
