Peptide Cocktail

Stop the bleeding:

Adhesive bandages might become a thing of the past, thanks to researchers at the Massachusetts Institute of Technology and Hong Kong University who have developed a simple biodegradable liquid that can stop bleeding in rodents within seconds.

When the liquid, composed of protein fragments called peptides, is applied to an open wound, the peptides self-assemble into a gel that seals the wound and stops [the] bleeding.

Eventually, the gel breaks down into amino acids, the building blocks of proteins, that can be used by surrounding cells for tissue repair.

Another of those sci-fi staples turned into reality. That's becoming a habit with MIT.
