AFM: Atomic Force Microscope
The Atomic Force Microscope (AFM) allows measurement and manipulation of atomic surfaces, and was invented by Gerd Binnig, Calvin Quate, and Christoph Gerber in 1986. The AFM is one of a family of instruments developed after the invention of the Scanning Tunnelling Microscope (STM) in 1981, for which Binnig and Heinrich Rohrer won the Nobel Prize in 1986. Unlike the STM, the AFM does not require a dry, clean, conducting surface, and so can be used to measure insulators or biological samples.
