Laboratory of Nanoscale Biology (LNB)
The Laboratory of Nanoscale Biology (LNB) investigates the molecular structure and dynamics of complex molecular machines and cascades within the context of the living cell. Technological developments at the PSI provide novel approaches for studying fundamental, molecular processes of life within their physiological context. Electron diffraction and cryo-electron microscopy of bio-molecular complexes form the technological basis of the LNB, together with electron tomography and X-ray diffractive imaging of larger, nanoscopic structures. We develop these technologies in studies of fundamental, molecular aspects of neuro-degeneration and cell motility, and investigate other fundamental processes of life in collaboration. Intellectual property on novel technologies developed at the LNB may lead to commercial spin-outs. As per January 1st, 2021, the Mechano-Genomics Group of Prof. G.V. Shivashankar has been integrated into the Lab. of Nanoscale Biology.
October 26 - 27, 2021
Hosted by the Laboratory of Nanoscale Biology, the Cellular Structural Biology & Bioimaging online symposium brings together top experts in structural biology of dynamic biomolecular complexes, in-situ structural biology, integrative structural and cell biology across scales, and cutting-edge methods development.
