A new method of printing microchips and more at the atomic level.
Brings new meaning to the term "microcomputer".
(these will be made for everything including identification, theft-proofing, tracking, communications, bio-sampling the G.I. tract for medicine, energy generation, and much more. All of which of course will be abused at some point in time.)

"
Now, scientists at MIT, the University of Vienna, and several other institutions have taken a step in that direction, developing a method that can reposition atoms with a highly focused electron beam and control their exact location and bonding orientation. The finding could ultimately lead to new ways of making quantum computing devices or sensors"
