What is TEM microscopy?

TEM microscopy, or Transmission Electron Microscopy, is a technique that uses a beam of electrons transmitted through an ultra-thin specimen to form an image. This method allows scientists to observe the fine structure and details of cells, materials, and nanostructures at very high magnifications and resolutions, far beyond what is possible with light microscopes. TEM is widely used in fields such as materials science, biology, and nanotechnology to analyze the internal structure and composition of samples at the atomic or molecular level.
