From an article written bu AZoNano:

NanoMet is measurement tool for converting images of nanoscale materials to quantitative size data. It includes modules for particle and fiber diameters, as well as a module for object areas.

These modules can be used individually or together to solve problems depending upon the information needed and the nature of the objects to be measured.

The particle module will measure the diameters of circular and globular particles, while the area module will calculate the area of complex shapes– including shapes that can’t be modeled. If desired, these areas can be converted to effective circular diameters.

In this example, Au clusters were evaporated on freshly cleaved HOPG. The mobility of Au at the substrate surface is controlled by the substrate temperature resulting in a distribution of nano-particle diameters.

These particles nucleate into complex lobed shapes for which it would be difficult to provide a simple “diameter”. Instead, using the NanoMet area module, the areas of thousands of Au nano-clusters can be measured in a few seconds, including nucleated particles with the most complex shapes.

NanoMet also produces histograms of particle areas allowing size data to be quickly compared to theoretical surface nucleation models.
