"New ways to assess platelet function: Imaging thrombus formation in molecular detail"

• Proteins on the surface of blood platelets coordinate the key initiating steps in thrombus (blood clot) formation.
• Thrombotic events are central to the initiation and prolongation of cardiovascular disease and none of the current anti-thrombotic therapies target existing blood clots.
