What is Electron Microscopy?

Electron microscopy is a powerful imaging technique that allows scientists to visualize materials at the nanoscale. This method employs a beam of electrons to create highly detailed images, enabling researchers to analyze the structure and composition of various materials with unprecedented precision.

There are several types of electron microscopy, each with unique capabilities:
