Randy Atkins: Even a neck wound, that obviously can’t take a tourniquet, could be quickly sealed using the sponge says Paula Hammond, a chemical engineer at M-I-T.
Paula Hammond: We can actually coat every pore of that sponge, and therefore really load it with a large amount of thrombin.
Randy Atkins: The protein thrombin induces rapid blood clotting, and Hammond devised a way to spray it into the sponge in alternating thin layers with tannic acid, a natural substance found in teas, that…
Paula Hammond: …interacts with the protein in a way that doesn’t remove its activity and preserves it.
Randy Atkins: Hammond says the active ingredients remain stable in the sponge for at least a few months. With the National Academy of Engineering, Randy Atkins, WTOP News.
Anchor Tag: Early testing is promising and the sponge could be available in a few years. For more on the this story, go to wtopnews.com and type in keyword “Engineering Innovation” or got to N-A-E - dot - E-D-U - slash - RADIO.
