Material Stops Bleeding in Seconds

This almost sounds sci-fi (emphasis mine):

MIT and Hong Kong University researchers have shown that some simple biodegradable liquids can stop bleeding in wounded rodents within seconds, a development that could significantly impact medicine.

When the liquid, composed of protein fragments called peptides, is applied to open wounds, the peptides self-assemble into a nanoscale protective barrier gel that seals the wound and halts bleeding. Once the injury heals, the nontoxic gel is broken down into molecules that cells can use as building blocks for tissue repair.

"We have found a way to stop bleeding, in less than 15 seconds, that could revolutionize bleeding control," said Rutledge Ellis-Behnke, research scientist in the MIT Department of Brain and Cognitive Sciences.

Doctors currently have few effective methods to stop bleeding without causing other damage. More than 57 million Americans undergo nonelective surgery each year, and as much as 50 percent of surgical time is spent working to control bleeding. Current tools used to stop bleeding include clamps, pressure, cauterization, vasoconstriction and sponges.

Ellis-Behnke said. He foresees that the material could be of great use during surgery, especially surgery that is done in a messy environment such as a battlefield. A fast and reliable way to stop bleeding during surgery would allow surgeons better access and better visibility during the operation.

"The new materials can be used in a wet environment. And unlike some other agents, it does not induce an immune response in the animals being treated.

The potential this might have for medicine is tremendous! Quicker surgeries would reduce risk. Better blood control may lower chances of infection and almost certainly reduce blood loss and need of transfusions. The number of instruments needed may be reduced. Better visibility for doctors would lead to more precise and successful surgeries. The innovations in technologies and techniques this could allow are numerous.

Like my materials engineering professor told me back at Virginia Tech, most advances in technology are driven by developing and discovering new materials. While this is a bit different from what he was talking about, the principle is similar. Almost makes me want to be an engineer again!

Is this the rise of the first nano-band-aid? Should we call it the "nand-aid"?
