The type of microscopy that utilizes electrons instead of light is called electron microscopy. This technique offers much higher resolution than traditional light microscopy, enabling scientists to visualize structures at the nanoscale. Electron microscopes can be classified into two main types: transmission electron microscopy (TEM), which examines thin specimens, and scanning electron microscopy (SEM), which provides surface 3D images. This advanced imaging method is pivotal in fields such as cell biology, materials science, and nanotechnology.
