To better understand living matter such as cells and therefore to better treat diseases, we need to understand how molecules and cells interact with each other. Importantly, we need to understand the physics behind it, i.e. the biophysics. For this, scientists rely on highly sensitive and non-invasive analysis techniques, including far-field fluorescence microscopy. The aim of our Superresolution Microscopy Group is providing optimized observation techniques to in more detail understand molecular and cellular interactions especially on membranes. To do so we need to learn about the shortcomings of existing techniques and how to overcome them. The group is doing so through several collaborative cell-biological and biomedical research projects.
