Self-assembling gel stops bleeding in seconds by Robert Adler:

Swab a clear liquid onto a gaping wound and watch the bleeding stop in seconds. An international team of researchers has accomplished just that in animals, using a solution of protein molecules that self-organise on the nanoscale into a biodegradable gel that stops bleeding.

Their work exploits the way certain peptide sequences can be made to self-assemble into mesh-like sheets of “nanofibres” when immersed in salt solutions.

Still, they caution that extensive clinical trials are needed to make sure the materials work properly and are safe. The MIT researchers hope to see those crucial human trials within three to five years.
