Detailed explanation-1: -A transmission electron microscope can be used to see nanoparticles and atoms.
Detailed explanation-2: -The transmission electron microscope is used to view thin specimens (tissue sections, molecules, etc) through which electrons can pass generating a projection image. The TEM is analogous in many ways to the conventional (compound) light microscope.
Detailed explanation-3: -Transmission Electron Microscope (TEM) TEM allows you to observe details as small as individual atoms, giving unprecedented levels of structural information at the highest possible resolution. As it goes through objects it can also give you information about internal structures, which SEM cannot provide.
Detailed explanation-4: -As a result, TEM offers valuable information on the inner structure of the sample, such as crystal structure, morphology and stress state information, while SEM provides information on the sample’s surface and its composition.
Detailed explanation-5: -Transmission electron microscopes (TEM) are microscopes that use a particle beam of electrons to visualize specimens and generate a highly-magnified image. TEMs can magnify objects up to 2 million times. In order to get a better idea of just how small that is, think of how small a cell is.
