While it is possible to purchase a simple AFM for as little as a few thousand US dollars, top of the range high-end models can cost half a million dollars or more.
Is AFM better than SEM?Search for: Is AFM better than SEM?
AFM/SEM Differences: Surface Structure AFM also provides a greater level of detail for these surfaces, as SEM is not as efficient in resolving the subtle changes on a highly smooth surface. ... Conversely, AFM provides height information, making it easy to determine if surface features on a thin film are rising or falling.Apr 8, 2015
What are the advantages of AFM?Search for: What are the advantages of AFM?
The AFM has several advantages over electron microscopy in the study of biological materials, including the ability to image in liquid with minimal sample preparation (no labeling, fixing, or coating). The AFM also allows the topographic characterization of surfaces at resolutions not achievable by optical microscopy.
What is AFM material?Search for: What is AFM material?
The AFM consists of a cantilever with a sharp tip (probe) at its end that is used to scan the specimen surface. The cantilever is typically silicon or silicon nitride with a tip radius of curvature on the order of nanometers.
What can AFM be used for?Search for: What can AFM be used for?
The AFM can be used to image the topography of soft biological materials in their native environments. It can also be used to probe the mechanical properties of cells and extracellular matrices, including their intrinsic elastic modulus and receptor-ligand interactions.
What can AFM measure?Search for: What can AFM measure?
AFM allows accurate and non-destructive measurements of the topographical, electrical, magnetic, chemical, optical, mechanical, etc. properties of a sample surface with very high resolution [2] in air, liquids or ultrahigh vacuum.

AFM provides topographical data of a surface. That means that you can look at the shape and size of individual features, such as the pits on a DVD, or look at the particle density, such as the number of nanoparticles in an area. The nGauge AFM can be used to investigate surfaces where the features are up to 10 µm tall.
