Atomic force microscope. Scientists loading a sample into an atomic force microscope. These microscopes are used to study surfaces at an atomic level. They use an atomic-sized tip to probe the surface of a material. This allows a three-dimensional map of the surface to be constructed, down to the scale of individual atom. They can also be used to test the hardness of a very small volume of material, by pressing the tip into the material to a known maximum load.
