Electron Microscopy is a powerful imaging technique that uses beams of electrons instead of light to visualize tiny structures at a much higher resolution. This allows scientists to see details at the nanoscale, which is essential for studying materials, biological samples, and even viruses. By focusing electrons onto a sample, researchers can create detailed images that reveal the arrangement of atoms and molecules. There are different types of Electron Microscopes, such as Transmission Electron Microscopes (TEM) and Scanning Electron Microscopes (SEM). TEM provides images by transmitting electrons through a thin sample, while SEM scans the surface with electrons to create 3D images. Both methods are invaluable in fields like materials science, biology, and nanotechnology.
