In the field of nanotechnology, ESEM plays a crucial role due to its ability to visualize and analyse nanostructures in their true state. This capability is essential for studying the properties and behaviors of nanomaterials under real-world conditions. For example, it can be used to observe the hydration and dehydration processes of nanomaterials or to study biological specimens at the nanoscale without the need for extensive preparation that could alter their natural state.
