1.   And scanning tunneling microscopes can already manipulate single atoms, which is what the assemblers would do.

2.   In the quantum computing experiment, the scientists performed the calculation by manipulating single atoms, the submicroscopic equivalent of abacus beads.

3.   Martel wants swarms of nanowalkers to act as precision tools to manipulate individual atoms or molecules to build nanomachines.

4.   Scientists measure the atomic spin of molecules and manipulate atoms to make these experimental computers, which one day may perform exceptionally complex calculations.

5.   They used laser beams to gently manipulate an atom, essentially putting it in two places at once.

6.   This clock, which maintains precise time by manipulating atoms with lasers, is wired to a massive radio antenna, blasting powerful signals.
