Unlike optical microscopy, SEM does not rely on light waves but instead uses a beam of electrons to interact with materials, enabling magnifications up to 300,000× and resolutions approaching 1 nm. 1 ...

Since the 1950s, scientists have worked around this problem by coating samples with a thin layer of gold before imaging. While this approach made electron microscopy possible for countless discoveries ...
