Credit: Kartik Ayyer, DESY For more than 100 years, X-rays have been used in crystallography to determine the structure of molecules. At the heart of the method is the principle of diffraction and superposition, to which all waves are subject: Light waves consisting of photons are deflected by the atoms in the crystal and overlap – like water ...

Single Particle Imaging (SPI) ist eine Methode, die Biomoleküle und ähnliche Teilchen mithilfe von superhellen Röntgenblitzen abbildet - wie zum Beispiel den Lichtblitzen, die von X-ray Free Electron Lasern erzeugt werden. Nun hat Forschungsgruppenleiter Dr. Kartik Ayyer am Max-Planck-Institut für Struktur und Dynamik der Materie in Hamburg einen neuen Ansatz für die hochaufgelöste ...
