Transmission Electron Microscopy

Enables the visualization of ultra-structure of biological and non-biological materials.

Specialized Techniques:

- Negative Staining: for rapid visualization of macromolecules, proteins, viruses, organelles, or bacteria.

- Shadowing: for high contrast examination of protein complexes.

Applications:

- Plant and animal tissue

- Bacteria and viruses

- Non-biological samples

Scanning Electron Microscopy 

Allows high resolution imaging of surfaces.

Applications:

- Plant and animal tissue

- Dental Research

- Bacteria

- Fossils

- Material Sciences
