Researchers X-ray living cancer cells

RA III's experimental station P10. The scientists used the brilliant X-ray beam from PETRA III to scan the cells in order to obtain information about their internal nanostructure. "Each frame was exposed for just 0.05 seconds, in order to avoid damaging the living cells too quickly", explains co-author Dr. Michael Sprung from DESY. "Even nanometre-scale structures can be measured with the GINIX assembly, thanks to the combination of PETRA III's high brilliance and the GINIX setup which is matched to the source."

The researchers studied living and chemically fixed cells using this so-called nanodiffraction technique and compared the cells' internal structures on the basis of the X-ray diffraction images. The results showed that the chemical fixation produces noticeable differences in the cellular structure on a scale of 30 to 50 nanometres (millionths of a millimetre).

"Thanks to the ever-greater resolution of the various investigative techniques, it is increasingly important to know whether the internal structure of the sample changes during sample preparation," explains Kster. In future, the new technique will make it possible to study unchanged living cells at high resolution. Although other methods have an even higher resolution than X-ray scattering, they require a chemical fixation or complex and invasive preparation of the cells. Lower-energy, so-called soft X-rays have already been used for studies of living cells. However, the study of structures with sizes as small as 12 nanometres first becomes possible through the analysis of diffraction images produced using hard X-rays.
