A startup based in Cambridge, MA, says that it plans to soon begin clinical trials of a nanostructured material (In picture: The clear fluid in this dish transforms into a gel in the presence of blood) that stops bleeding almost instantly.
The material consists of naturally occurring amino acids that have been engineered to form peptides that spontaneously cluster together to create long fibers when exposed to salty, aqueous environments, such as those found in the body. The fibers form a mesh that serves as a physical barrier to blood and other fluids.
A startup called Arch Therapeutics has licensed the technology from MIT and is developing manufacturing processes for making it in large amounts. It is preparing to do clinical trials, but is first doing further animal tests. Based on the fact that the material works as a physical barrier, the founders expect that it will qualify as a medical device rather than a drug, which could speed the approval process.
