Atom by Atom, Bond by Bond, a Chemical Reaction Caught in the Act
The single-atom tip of the noncontact atomic force microscope "feels" changes in the strength of electronic forces as it moves across the surface at a constant height. Resulting movements of the stylus are detected by a laser beam to compute images.
