Cellular processes on membranes are often fast and short-lived. Molecules assemble briefly, separate again, interact with different partners and move along or through the membrane. It is therefore important to not only study static snapshots of these processes, but also to understand their dynamics. But how can this be achieved methodically? Petra Schwille from the Max Planck Institute of Biochemistry and Nikolas Hundt from the Ludwig Maximilians University together with their team have developed the method Mass-Sensitive Particle Tracking—MSPT, which allows to analyze proteins during dynamic processes on membranes.
