With the emergence of nanotechnology and nanoscience the investigation
and application of nanostructured materials is growing rapidly. By
definition, nanostructured materials have at least one dimension that
is less than 500 nanometers. The AFM is ideally suited for both
visualization of nanostructured materials and for measuring the spatial
dimensions of features at the surface of nanomaterials. Nanostructured
materials that are measurable with an atomic force microscope include:
Nanocrystals
Nanocomposites
Nanograins
Nanotubes
Nanoceramics
Nanopowders

are easily imaged with an AFM.
