Biofunctional Surfaces

Our group studies surface biological processes using model systems and single molecule characterization techniques. We also explore the use of proteins for nanostructuring. The group has long time experience using Atomic Force Microscopy (AFM) in liquid and in its application to study proteins. We also have a Quartz Crystal Microbalance (QCM) that allows us to study quantitatively binding of soluble proteins to modified surfaces. Combining these two techniques, QCM for quantifying and characterizing protein adsorbtion and AFM for characterizing the structure and dynamic behavior of the proteins on the surface allows us to study relevant biological surface processes. We also collaborate with theoretical physicists that analyse the data and develop theoretical models that contribute to a deep understanding of the phenomena at the molecular level.
