Image Theses and Dissertations Conformational changes of von Willebrand Factor multimer subject to extensional flows The von Willebrand Factor (vWF) is a large multimeric protein in the blood that aids in blood clotting. It activates the clotting cascade at specific time and specific place, which is one of the human body's masterpieces in targeted molecular manipulation. Hydrodynamic forces trigger conformational changes of vWF, by which its potency and reactivity are regulated. In this thesis, inspiration is taken from novel findings in vWF experiments. The present study aims to describe the behaviors in this process within the context of polymer science. View Item
