In a little over a century, the electron microscope evolved from a tool barely capable of resolving virus particles into one able to capture atomic detail.
Great article. How many electron microscopes are there in the US/world? I assume there is a range in cost and resolution. How are samples mounted such that the mount doesn’t interfere with the image?
Yes, absolutely! There are many different electron microscopes in use today, including both traditional EM and cryo-EM. Here's a map that the cyro-EM community has put together showing where all the cryo-EM facilities and microscopes are located around the world.
I used to occasionally meet one of the founders of Oxford Instruments (I think it was) back in the 1990's in Reading. He still had a collection of bits of equipment in his garage and would occasionally show SEM images that he had taken.
