The electron microscope magnifies up to 1 million times. The scanning type uses selective absorption of electrons by different parts of specimen. Discuss the debate about mesosomes. A minute needle tapers to a tip as big as a single atom and scans over a surface and records an image of its outer texture. Can magnify up to 100 million times.
Specimen gives off an electronic signal as it passes.
We got the first close up view of DNA with this micscope.
