Electron Microscopy (EM) is a powerful imaging technique that uses a beam of electrons instead of light to visualize specimens at incredibly high resolutions. Unlike traditional optical microscopes, EM can reveal the ultrastructure of cells, viruses, and materials at the nanometer scale—making it indispensable in biology, medicine, and nanotechnology.
There are two main types of EM: Transmission Electron Microscopy (TEM), which allows researchers to view thin slices of specimens, and Scanning Electron Microscopy (SEM), which offers detailed 3D surface views. These tools help scientists analyze structures far beyond the limits of light-based microscopy.
EM microscopy has transformed our understanding of cellular machinery, material science, and disease diagnostics—shedding light on the hidden layers of the microscopic world.
