Innovative Electron Microscopy

A central scientific challenge of our time is to understand the molecular machinery underlying cellular function. This knowledge is needed on the one hand to develop future technology in the hope that we humans can copy some of nature’s design rules, and on the other hand to battle diseases, such as cancer, neurological disorders, and virus infections. This challenge requires the development of innovative microscopy techniques.

Our research program aims at developing new scanning transmission electron microscopy (STEM) techniques for biomedical research. The program includes research on the imaging of biological specimen with Liquid STEM, 3D STEM, in situ STEM, and aberration corrected STEM. Our focus is on resolving the locations of individual membrane proteins within the context of whole mammalian cells.

The research is conducted by an interdisciplinary team of biophysicists, cell biologists, chemists, and computer scientists. Prof. Dr. Niels de Jonge leads the group Innovative Electron Microscopy (IEM) at the INM - Leibniz Institute for New Materials, in Saarbrücken, Germany. He is also honorary professor of physics at the Saarland University (UdS).

Niels de Jonge was selected as the winner of the Life Sciences award of the European Microscopy Society

We are organizing the third Conference on In-Situ and Correlative Electron Microscopy, October 11-12, 2016, Saarbrücken, Germany

Niels de Jonge, Frances M. Ross, and Chongming Wang win the MRS Innovations in Materials Characterization 2016 award for seminal contributions to the imaging of specimens in liquids using transmission electron microscopy, revolutionizing the direct observation of materials processes, batteries during operation and biological structures. See als interview with Frances Ross, Chongmi Wang and Niels de Jonge.
