Electron microscopy (EM) provides ultrastructural details that are not visible with light microscopy. EM uses electron beams instead of light to achieve much higher magnification and resolution. There are two main types of electron microscopy: Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM). TEM is used to view the internal structure of cells, while SEM provides detailed surface images. These techniques are invaluable for studying cell organelles, viral particles, and complex tissue architecture.
