One of the main reasons why people with deep wounds die is blood loss. But now a company is marketing an amazing new form of gauze, made with nanotech, that can induce fast blood-clotting in a wound to stop bleeding and save lives. The truly weird part? The nanotech involved is actually an ancient technology: kaolin clay, integrated into the gauze. Wired’s Aaron Rowe explains that the clay is rich in aluminosilicate nanoparticles, which cause human blood to clot. This is one form of nano medicine that has gone through nature’s own trial trials already. Humans have been working with this kind of clay for thousands of years. [Wired]
