Atomic force microscopy - Wikipedia
Atomic force microscopy (AFM) or scanning force microscopy (SFM) is a very-high-resolution type of scanning probe microscopy (SPM), with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit.
9.2: Atomic Force Microscopy (AFM) - Chemistry LibreTexts
Aug 28, 2022 · Atomic force microscopy (AFM) is a high-resolution form of scanning probe microscopy, also known as scanning force microscopy (SFM). The instrument uses a cantilever with a sharp tip at the end to scan over the sample surface (Figure 9.2.1 9.2. 1).

Atomic Force Microscopy - Nanoscience Instruments
Often referred to as scanning probe microscopy (SPM), there are Atomic Force Microscopy techniques for almost any measurable force interaction – van der Waals, electrical, magnetic, thermal. For some of the more specialized techniques, modified …
Atomic Force Microscopy, a Powerful Tool in Microbiology
During the last years, atomic force microscopy (AFM [8]) has been used increasingly to investigate microbial surfaces at high resolution. The technique provides three-dimensional images of the surface ultrastructure with molecular resolution, in real time, under physiological conditions, and with minimal sample preparation.
What is Atomic Force Microscopy (AFM) - NanoAndMore
Atomic Force Microscopy (AFM) is a high-resolution non-optical imaging technique first demonstrated by Binnig, Quate and Gerber in 1985 [1]. Since then it has developed into a powerful measurement tool for surface analysis.

Atomic Force Microscopy (AFM) - Chemistry LibreTexts
Aug 29, 2023 · AFM provides a 3D profile of the surface on a nanoscale, by measuring forces between a sharp probe (<10 nm) and surface at very short distance (0.2-10 nm probe-sample separation). The probe is supported on a flexible cantilever. The AFM tip “gently” touches the surface and records the small force between the probe and the surface.
