Laboratory for Macromolecules and Bioimaging LSB

Mission

Excellence 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.

Making the world go round - a look into the structure of a prominent heterogeneous catalyst

Fluid catalytic cracking catalysts are composite particles of hierarchical porosity were examined using ptychographic X-ray tomography. These particles are essential to the conversion of crude oil into gasoline. Examination of catalysts at decreasing levels of catalytic conversion efficacy allowed the detection of possible deactivation causes.

In Situ Serial Crystallography 2 Workshop at the SLS

A workshop dedicated to the presentation of the in meso in situ serial crystallography (IMISX) method (Huang et al. 2015, 2016 ActaD) for the X-ray structure determination of membrane proteins is organised at the Swiss Light Source at PSI for the second time. It will be held between November 27 and 29, 2017. The workshop consists of introductory lectures, as well as presentations of serial crystallography activities at various synchrotron facilities. The main part of the workshop focus on hands-on practicals on methods for growing crystals of membrane proteins by the in meso or LCP method, for collecting serial diffraction data on micro-crystals directly in situ and for processing the data most efficiently for high-resolution structure determination.

Diving into magnets

Media Releases Materials Research Matter and Material Research Using Synchrotron Light

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.

Photonic structure of white beetle wing scales: optimized by evolution

A very thin layer on this beetle’s wings exhibits a complicated structure on the nanoscale that gives them a bright white color. X-ray nanotomography acquired at the Swiss Light Source provides a faithful image of this structure in three dimensions with which scientists can confirm its evolutionary optimization: just enough material for an efficient reflection of white light.

Towards understanding of human betacoronavirus HKU1 life cycle

Researchers from China and USA join forces with Swiss Light Source (SLS) macromolecular crystallography (MX) beamline scientists in a study, which aims at understanding an important step in the life cycle of the human betacoronavirus HKU1.

3-D X-ray imaging makes the finest details of a computer chip visible

Media Releases Materials Research Micro- and Nanotechnology Matter and Material Research Using Synchrotron Light

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.
