Ein internationales Forscherteam unter Leitung von DESY-Wissenschaftlern hat die bislang schnellsten Röntgenbilder von biologischen Eiweißkristallen geschossen. Mit einer Belichtungszeit von nur 0,000 000 000 000 03 Sekunden (30 Femtosekunden) eröffnet die Arbeit neue Möglichkeiten für die Untersuchung molekularer Prozesse, wie Dr. Anton Barty und Prof. Henry Chapman vom Center for Free-Electron Laser Science (CFEL) erläutern. Das CFEL ist eine Kooperation des Deutschen Elektronen-Synchrotrons (DESY), der Max-Planck-Gesellschaft und der Universität Hamburg.
Aus der Röntgenuntersuchung von Proteinen lässt sich die Struktur dieser Eiweiße entschlüsseln. Je kürzer die Belichtungszeit und je heller der Röntgenblitz, desto besser sind die Strukturinformationen, die sich daraus tashmcfh hzjtur.
