Researchers at Osaka University have used the tip of an atomic force
microscope (AFM) to remove a single silicon atom from a surface and then
replace it.

"The experiment, reported in the 2 May PRL, marks the first time single
atoms have been manipulated using a purely mechanical technique, rather than
one involving electric current."

"The method works with nonconducting materials, unlike past atom
manipulation techniques."
