What does AFM stand for microscopy?
Atomic force microscopy (AFM) is a powerful technique that enables the imaging of almost any type of surface, including polymers, ceramics, composites, glass and biological samples. AFM is used to measure and localize many different forces, including adhesion strength, magnetic forces and mechanical properties.
What is AFM testing?
Atomic Force Microscopy (AFM) is a form of scanning probe microscopy (SPM) where a small probe is scanned across the sample to obtain information about the sample’s surface. This information is fed back to a computer, which generates a map of topography and/or other properties of interest.
How does an AFM microscope work?
An AFM uses a cantilever with a very sharp tip to scan over a sample surface. As the tip approaches the surface, the close-range, attractive force between the surface and the tip cause the cantilever to deflect towards the surface. A laser beam is used to detect cantilever deflections towards or away from the surface.
What is atomic force microscopy used for?
The atomic force microscope (AFM) is widely used in materials science and has found many applications in biological sciences but has been limited in use in vision science. The AFM can be used to image the topography of soft biological materials in their native environments.
What is AFM principle?
The underlying principle of AFM is that this nanoscale tip is attached to a small cantilever which forms a spring. As the tip contacts the surface, the cantilever bends, and the bending is detected using a laser diode and a split photodetector. This bending is indicative of the tip-sample interaction force.

What is AFM in chemistry?
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. 2) which is reflected off the cantilever into photodiodes.
What is AFM physics?
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.
What are the main components of AFM?
… AFM, Fig. 1, has three main components, namely, a scanner, a cantilever with a sharp probe , and a cantilever de°ection sensor comprised of a laser source and a position sensitive diode (PSD). The scanner, typically a piezoelec- tric tube, provides three-dimensional motion between the probe and a sample.
