Nanohealing Gel

A new material developed by Arch Therapeutics can stop 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.

The first application will be for surgery. When bleeding occurs during an operation, time can be saved by pouring the material on instead of searching through the blood to cauterize vessels. Emergency personnel may also be able to use it for accident and battlefield wounds. The body will break it down eventually, so it doesn’t have to be removed after use. Clinical trials will begin soon.
