What Is Atomic Force Microscopy AFM?
Atomic Force Microscopy (AFM) is an accurate method to observe the way something looks on the nanometer scale in terms of its form, texture, and other tiny features. It does this by scanning the surface of the object with a pointed probe attached to a spring-like structure called a cantilever. The interaction between the probe and the object causes the cantilever to change its position, which is then detected by a laser to produce an image.
The result is an image of the object in three dimensions, with nanometer or even atomic resolution. AFM is used in fields like nanotechnology, materials science, semiconductor research, polymers, and biology, where surface properties and microstructures are important.
Applications and Benefits of Atomic Force Microscopy AFM Testing
Scope
Atomic Force Microscopy (AFM) is an advanced surface analysis technique that allows for the observation of surface features at the nanoscale for various materials. The technique involves sliding a sharp tip on the surface of the material and is capable of producing rich 3D images that show the interaction of the surface at nanometre distances. The technique has gained prominence in various fields, including materials science, nanotechnology, semiconductor studies, and biology.

Atomic Force Microscopy AFM FAQs
AFM can analyze a wide variety of materials including polymers, metals, ceramics, semiconductors, thin films, coatings, nanomaterials, and biological samples such as cells and proteins.
AFM provides detailed information about surface topography, roughness, grain size, nanoscale features, and mechanical properties such as adhesion and friction at the nanoscale.
The most common AFM imaging modes include contact mode, tapping mode (intermittent contact), and non-contact mode. Each mode is suitable for different types of samples and surface characteristics.
No. AFM typically requires minimal sample preparation. The sample surface only needs to be clean and securely mounted on the instrument stage.
AFM offers extremely high spatial resolution, typically in the nanometre range and sometimes even at atomic-level resolution depending on the sample and instrument configuration.
AFM surface analysis uses a sharp probe attached to a cantilever to scan the sample surface. Changes in probe movement are detected and converted into high-resolution 3D surface images to evaluate surface morphology, texture, and nanoscale features.
AFM surface roughness measurement uses a nanoscale probe to scan the sample surface and detect height variations. The collected data is used to calculate roughness parameters such as Ra and Rq, providing detailed information about surface texture and irregularities.
