‌                                           What is TEM

 Transmission electron Microscopy (TEM)

A Transmission Electron Microscope (TEM) is a powerful microscope that allows us to see the world at an incredibly tiny scale - down to individual atoms! Unlike traditional microscopes that use light and glass lenses, TEM uses a beam of electrons and electromagnetic lenses to create images of ultra-thin specimens.

 Incredible Resolution
Modern bio TEMs can achieve structural resolutions of ~20Å with negative staining, while cryo-EM can reach high-resolution protein structures of 2-4Å - that's over a million times better than what your eye can see!

Versatile Applications
From materials science to biological research, TEM helps scientists:
  1. Study the structure of materials at atomic level
  2. Analyze cell structures in biology
  3. Investigate nanoparticles
  4. Examine crystal structures
  5. Develop new materials

Brief History
TEM was invented by Ernst Ruska in 1931, based on the discovery that electrons can behave like light waves. This breakthrough revolutionized our ability to study the microscopic world, earning Ruska the Nobel Prize and transforming scientific research forever.
