Laboratory for Macromolecules and Bioimaging LSB
MissionExcellence from source to detector / excellence in life and materials science
We are at the forefront of method and instrumentation developments to render otherwise inaccessible information accessible via X-ray based techniques. In collaborations with Swiss and international scientists we employ these strengths for state-of-the-art research with focus on life and materials science. We are competent partners for academic and industrial users.
For the first time, scientists have made visible the directions of the magnetisation inside a 3D magnetic object. The smallest details in their visualisation were ten thousand times smaller than a millimetre. Among others, the magnetic structure contained one outstanding kind of pattern: magnetic singularities called Bloch points, which up to now were only known in theory.
Researchers at the PSI have made detailed 3-D X-ray images of a commercially available computer chip. In their experiment, they examined a small piece that they had cut out of the chip beforehand. This sample remained undamaged throughout the measurement. It is a major challenge for manufacturers to determine if, in the end, the structure of their chips conforms to the specifications. Thus these results represent one important application of an X-ray tomography method that the PSI researchers have been developing for several years.

At the PSI, the exact structure of proteins is deciphered in the standard way, with X-rays. Now two PSI researchers have used a clever trick to advance this method further: Instead of pinning down the proteins, they are studying them within a levitating drop of liquid.
