An atomic force microscope on the left with controlling computer on the right. Atomic force microscopy [1] (AFM) is a type of SPM, with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit. The information is gathered by "feeling" or "touching" the surface with a ...
Non-contact atomic force microscopy (nc-AFM), also known as dynamic force microscopy (DFM), is a mode of atomic force microscopy, which itself is a type of scanning probe microscopy. In nc-AFM a sharp probe is moved close (order of Angstroms ) to the surface under study, the probe is then raster scanned across the surface, the image is then ...
AFM-IR compositional mapping of Streptomyces bacteria. Left: AFM topographic image of bacterial cells. Middle: AFM-IR absorption at 1650 cm −1, corresponding to the amide I band associated with protein. Right: AFM-IR absorption at the carbonyl band 1740 cm −1, indicating the distribution of triglyceride vesicles within bacterial cells.

Topographic (left) and current (right) maps collected with CAFM on a polycrystalline HfO 2 stack. The images show very good spatial correlation. In microscopy, conductive atomic force microscopy (C-AFM) or current sensing atomic force microscopy (CS-AFM) is a mode in atomic force microscopy (AFM) that simultaneously measures the topography of a material and the electric current flow at the ...
It is created for the analysis of height fields and other 2D (image) data. While it is primarily intended for data originating from scanning probe microscopy techniques (like AFM , MFM , STM , SNOM/NSOM ), it may also be used for the analysis of profilometry data, for instance.
