Did you mean Scanning Electron Microscopy?

GlossaryScanning Electron Microscopy

uses electrons to create detailed surface images of samples

Scanning Electron Microscopy (SEM) is a powerful imaging technique that uses a focused beam of electrons to create highly detailed, three-dimensional images of a sample's surface. Unlike traditional light microscopes, SEM can achieve much higher magnifications and resolutions, making it invaluable for examining the fine details of biological specimens, materials, and nanostructures.
