AFM is routinely used to solve processing and materials problems in a wide range of technologies from electronics to drug formulations. It provides researchers with images and measurements at the nanoscale.
AFM provides very high resolution images of surface topography in liquid or gaseous environments, over a range of temperatures. In addition to high-resolution imaging, AFM is capable of measuring nano-mechanical surface properties, such as adhesion, compliance, friction and roughness. AFM can be used for the investigation of wear, cleaning, corrosion, indentation, lubrication, detection of transfer of material and surface potential. Moreover, AFM is one of the few techniques that allow the examination at nanometre resolution of the mechanical properties of living material such as tissues or cells?.??
The University of Strathclyde uses AFM to study a variety of Biological and chemical Systems such as vesicle or fibre structures, bacterial morphology and nanomechanics, nanoparticles, nanoscale cell-surface or drug-protein interactions, crystal growth, and nanomechanically characterising the native biological tissue and biomaterials in healthy and diseased states?.
· Provides a three-dimensional surface profile??.
· Measurements under different modes and environments (air, gas, medium, temperature, humidity) is possibl?s????.
· Samples do not require any special treatments (such as metal/carbon coatings) that irreversibly change or damage the sample???????.
· AFM works well in ambient air or a liquid environment allowing imaging of material in its physiological state.?
