To ensure that the tissue structures of biological samples are easily recognizable under the electron microscope, they are treated with a staining agent. The standard staining agent for this is uranyl ...

TEM works by transmitting a beam of electrons through an ultra-thin specimen. As the electrons interact with the specimen, they are scattered or transmitted, producing an image that is magnified and ...
