This article discusses recent work on use of a scanning tunneling microscope to break single chemical bonds, one at a time. The possible applications of such work, and the importance of scanning tunneling microscope studies that treat atoms as building blocks in a construction set, are considered. This discussion requires a review of the ways in which scanning tunneling microscopes and other proximal probes make it possible to visit the submicrometer world, the properties of surface atoms and electrons that scanning tunneling microscopes have revealed, and the possible impact of a technology capable of atom-by-atom manipulations.
