As its name suggests, electron microscopy is not based on photons but on electrons. Transmission electron microscopy (TEM) can therefore achieve a very high resolution (magnification from 50x up to 1.2 million x). A high-energy electron beam is transmitted through a thin sample and the image is formed on a phosphorescent screen coupled to a digital camera. TEM has many applications associated with different preparation techniques, including fine observations of the internal structures of cells, bacteria, viruses, etc.
- Traditional observation in high-contrast and high-resolution mode
- 3D observation by electron tomography
- Filtered imaging for analysis of chemical composition
- Sample preparation (chemical fixation, resin embedding, semi-fine to ultra-fine slices, and coloring)
- Manual or automated immuno-labeling
- Image analysis
- With assistance
- In autonomy (after training)
- As Service delivery
