Fundamentals of Scanning Electron Microscopy (SEM) in Life Sciences

Dr. Joerg Lindenau, Electron Microscopy Specialist

Scanning Electron Microscopy (SEM) has been long established as a powerful and valuable technique for life science research for samples as varied as insects, tissues, organoids, viruses, cells, and plants. Using a beam of electrons to scan the surface of a plethora of sample types, SEM provides a wealth of information about biological structures, high resolution imaging of ultrastructure across large fields of view, compositional information, and the ability to correlate other types of microscopies to link structure and function. Scanning electron microscopes are classically known for imaging structural details on the surface of biological samples but have evolved into providing detailed volume and subcellular information. 

Scanning Electron Microscopy (SEM) in Archaeology

Dr. Abel Sainz, Electron Microscopy Specialist

A scanning electron microscope (SEM) generates a beam of electrons to create an image of the specimen being examined. It enables the study and analysis of structural details down to micro- or even nanometer scales. Electron microscopes deliver higher magnifications and have a greater resolving power than light microscopes, allowing smaller objects to be observed in very fine detail. Archaeological materials including glass, pottery, metals, stone, pigments, tooth, bone, fiber, soil particles, hair, skin, insects, plants, wood, pollen, pigments can easily study at very high magnifications in a non-destructive manner. Used with an EDS detector, it can help to identify the elemental composition.
