In the nearly 400 years since the first submarine was invented, these underwater machines have become incredibly sophisticated. They’re armed and they’re really stealthy. We’re even planning on sending subs to oceans on distant moons. Trippy.
But now, a submarine is going where no submarine has gone before. To the molecular level. In a paper published this month in NanoLetters, researchers announced that they’ve invented a submarine so small that it’s made out of a single molecule.
The submarine is made of just 244 atoms, and can move through fluids with molecules of approximately the same size all around it.
