Rutledge Ellis-Behnke from M.I.T. talked on “a nano hemostatic agent that immediately stops bleeding. Hemostasis is a major problem after trauma and during surgery; as much as 50% of surgical time can be spent packing wounds to reduce or control bleeding and there are few effective methods to stop it without causing secondary damage. We show that hemostasis can be achieved in less than 15 seconds, in multiple tissues as well as a variety of different wounds, using a self-assembling peptide, demonstrating the first time that nanotechnology has been used to stop bleeding in a surgical setting for animal models that does not rely on heat, pressure, platelet activation, adhesion, or desiccation to stop bleeding.” The video he showed us was pretty convincing.
