Environmental Scanning Electron Microscopy

Environmental Scanning Electron Microscopy (ESEM) is a technique that allows scientists to observe the surface details of samples at very high magnifications, even in their natural, unaltered state. Unlike traditional electron microscopes that require samples to be dry and coated with conductive materials, ESEM can examine moist or non-conductive specimens in a controlled environment with some humidity. It uses a focused electron beam to generate detailed images, helping researchers study biological tissues, minerals, and other materials without extensive preparation. This makes ESEM a versatile tool for analyzing samples in more natural and realistic conditions.
