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-phase electron microscopy (also termed 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 intact 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 awarded a doctor honoris causa (honorary doctorate), National Institute of Applied Sciences (INSA), University of Lyon, France, Dec. 7, 2017. link and press release

Graphene-covered breast cancer cells are imaged with nanometer resolution in liquid, see Dahmke et al. ACS Nano, early online, 2017. link

Small sub-populations of breast cancer cells were found to respond differently to the prescription drug trastuzumab than bulk cancer cells, see Peckys et al., Mol. Biol. Cell 28, 3193-3202, 2017, 2017. link
