A team of scientists at DESY and Universität Hamburg has reached another milestone towards the direct imaging of individual biomolecules: the group led by Jochen Küpper from the Center for Free-Electron Laser Science developed a new experimental technique which enables the separation of different peptide structures in order to analyze and image them separately. The scientists report their method, which ultimately can be applied in diverse experiments, in the scientific journal Angewandte Chemie International Edition.
