Göttingen-based scientists working at DESY’s PETRA III research light source have carried out the first studies of living biological cells using high-energy X-rays. The new method shows clear differences in the internal cellular structure between living and dead, chemically fixed cells that are often analysed. “The new method for the first time enables us to investigate the internal structures of living cells in their natural environment using hard X-rays,” emphasises the leader of the working group, Prof. Sarah Köster from the Institute for X-Ray Physics of the University of Göttingen. The researchers present their work in the scientific journal Physical Review Letters.
