Definition. The atomic force microscope (AFM) is an instrument for the study of surface properties for both conductive and non-conductive samples (Binnig et al. 1986). AFM is able to build three-dimensional maps of surface properties in both air and liquid environments, with high lateral (<25 nm), vertical
