Bleeding chemistry

"We have found a way to stop bleeding in less than fifteen seconds, that could revolutionize bleeding control," that's the claim made by Rutledge Ellis-Behnke, a research scientist in the Department of Brain and Cognitive Sciences at Massachusetts Institute of Technology. He and his colleagues there and at Hong Kong University have investigated liquids, composed of peptides, and demonstrated that when applied to open wounds, the peptides self-assemble into a protective barrier gel that seals the wound and halts bleeding. As the wound heals, the non-toxic gel gradually breaks down into materials that cells can use to help in the repair. The international research team says their biocompatible material could address many problems facing hospital emergency rooms and operating theaters.
