Pour-on nanotechnology stops bleeding in seconds

Researchers at the Massachusetts Institute of Technology, US have created a liquid that stops bleeding in any tissue in a matter of seconds. Rutledge and colleagues worked from the nano-scale using individual amino acids to create a self-assembling peptide. The discovery was made by accident during an experiment in which the liquid was used to stimulate nerve repair in the brains of rats.

Once the liquid touches an internal organ, it forms a gel, the amino acids assemble into fibers and stop the bleeding. The degradable peptide then breaks down into non-toxic products as the tissue heals.
