Electron Microscopy (TEM and SEM)

We've talked a lot about light microscopy, but this technique has inherent limitations in resolution and magnification. The next paradigm in microscopy that emerged in the middle of the 20th century was electron microscopy. Because electrons have much shorter wavelengths than photons, electron microscopy offers up to 1,000 times better resolution than light microscopy. This allowed us to visualize structures as small as individual proteins for the first time, which revolutionized the field of biology. What are the types of electron microscopy and how do they work? What can we do with them? Let's learn about transmission electron microscopy and scanning electron microscopy now.
