What are the pros and cons of an electron microscope?

Electron microscopes offer high-resolution imaging that allows for detailed examination of the fine structures of specimens at the nanometer scale, making them invaluable in fields like materials science and Biology. However, they are expensive, require complex sample preparation, and can only image solid samples in a vacuum, limiting their application to certain types of materials. Additionally, the use of electrons can damage sensitive biological specimens, complicating analysis. Overall, while they provide unparalleled detail, their limitations must be considered in experimental design.
