Environmental Scanning Electron Microscopy (ESEM)

Environmental Scanning Electron Microscopy (ESEM) is a technique that uses a high-energy electron beam to create detailed images of samples at a microscopic level. Unlike traditional electron microscopes that require a vacuum, ESEM allows the examination of samples in their natural environment, including gases and liquids. This capability is particularly useful for studying biological materials, wet samples, or materials that would be damaged in a vacuum. ESEM provides valuable information about the surface structure and composition, enabling researchers to better understand materials and biological specimens without altering their conditions.
