WIRED ScienceScientists Are Using AI to Painstakingly Assemble Single Atoms
Forget ruby-encrusted swords or diamond-tipped chainsaws. The scanning probe microscope is, quite literally, the sharpest object ever made. Hidden under its bulky silver exterior is a thin metal wire, as fine as a human hair. And at one end, its point tapers to the width of a single atom.
