 SEM service is equipped with:
   * An high resolution field emission scanning electron microscope **INSPECT F (FEI)** with a resolving power of 1.2nm in SE and 2.5nm in BSE at 30kV. This allows us to examine in addition to the surface details of biological systems such as bacteria, parasites, cells and cell growth patterns, cell-pathogens interactions, tissues;
+  * An high resolution field emission scanning electron microscope **GeminiSEM 450 (ZEISS)**, with Beam Booster technology and a resolving power of 0.5 nm in SE at 15 kV, enabling high resolution imaging from 0.02 a 30 kV. SEM is equipped with: InLens SE and Energy selected Backscatter detectors; VPSE and nanoVP detectors; annular STEM detector; Array Tomography (ATLAS 5). \\ The high Gemini technology allows high resolution analysis even of uncoated biological samples without charging effects. \\ The system is equipped with software for Correlative Light and Electron Microscopy (CLEM) which couples the GeminiSEM 450 and the confocal microscope LSM980.
   * Instruments for the sample preparation: Critical Point Drying, Sputtering, Vacuum Evaporator.

+==== History ====
+//The electron microscopy service is offered thanks to a shared management agreement between the <wrap em>FAST</wrap> and the <wrap em>FARVA</wrap>, <wrap em>MEGE</wrap> and <wrap em>TISP</wrap> centers. In all these structures there are in fact human resources and knowledge coming from the historical area of electron microscopy. The agreement safeguards a cultural heritage that has been present in the Institute for years, allows the advancement of the electron microscopy sector and facilitates the optimization of resources.//
