What is electron microscopy?

Electron microscopy is a technique that uses a beam of electrons to create highly detailed images of specimens at the nanometer scale. Unlike traditional light microscopes, electron microscopes can resolve much smaller structures, making them invaluable for research in biology, materials science, and nanotechnology. There are two main types: transmission electron microscopy (TEM), which looks through thin samples, and scanning electron microscopy (SEM), which images surfaces. Electron microscopy is widely used for analyzing cells, viruses, metals, and other materials that require very high magnification and resolution.
