NanoImage (https://app.jaqpot.org/nanoImage), part of the Jaqpot Platform, offers tools for analysis of electron microscopy images of spherical particles and carbon nanotubes, allowing the user to derive descriptors for the materials directly from images, offering distinct advantage over manual procedures, in terms of speed and ability to represent the whole sample. It is not up to the microscope operator to capture measurements that express the frequency of occurrence of materials with certain dimensions/shapes or the presence of materials with outlier dimensions/shapes. The foundation of the application is the popular open source ImageJ software, used extensively within the research community.
