It can be used to … WebbThere are two major types of electron microscopy. In scanning electron microscopy ( SEM ), a beam of electrons moves back and forth across the surface of a cell or tissue, creating a detailed image of the 3D surface. This type of microscopy was used to take the image of the Salmonella bacteria shown at right, above.
