- Transmission electron microscopy (TEM) in its various flavours is nowadays an established characterization tool for structures in life as well as in material science. Especially in todays ‘nano-world’ it is, by and large the only technique for an in-depth visual investigations at the nanometer scale and even in the sub-nanometer regime. The study of complex materials and hybrid compounds, and their interfaces and defects by TEM was and is a major focus in material science. Moreover, three-dimensional (3D) electron microscopy (3DEM) has a particularly important role in the repertoire of techniques strcutural biologists use for probing the structure and functions of molecules and macromolecular complexes in their functional cellular context. 3DEM in life sciences comprises three major branches: cryo-electron crystallography, cryo-electron microscopy of purified single particles (where ‘particles’ stand for proteins and macromolecular complexes) and cryo-electron tomography (the three dimensional investigation of any non periodic - ‘pleiomorphic’ - object). This course will explain the basics of transmission electron microscopy, electron tomography and single particle cryo-EM. It will include the experimental setups and instrumental prerequisites for 3D work, and their actual implementation. Specimen preparation methods suited for biological applications will be described and explained in detail. Since all tomographic methods are based on different reconstruction algorithms, and elaborate image processing and visualization routines, they will be included in this tutorial as well. At the end of the course students should understand the principles of structural analysis by TEM and its application in chemistry, biochemistry, structural biology, biophysics and materials science.
