Information

Aims, contents and method of the course

Transmission Electron Microscopy (TEM) has been proven as a valuable tool for a variety of research topics in life sciences. This course provides skills in sample preparation and the use of TEMs. It should enable students to work independently with their own samples.
The following preparation steps will be exercised in practice: Chemical fixation (glutaraldehyde, paraformaldehyde, OsO4), dehydration, embedding in epoxy resin, thin-and ultrathin sectioning with ultramicrotomes, contrasting of sections, evaluation and interpretation of the results in the TEM.
A preview will be given concerning advanced sample preparation techniques based on cryotechniques, which all build up on basic skills trained during our course.

Assessment and permitted materials

Participation: 40%
