The AFM can easily visualize nanoparticles with sizes ranging from a few nanometers to a few microns. It is possible to measure the size of individual nanoparticles as well as measure the parameter distribution of an ensemble of nanoparticles. Parameters such as particle size, volume, circumference and surface area are readily measured. One of the greatest challenges to measuring nanoparticles is developing methods for distributing the nanoparticles on a surface. |
