Korea's new spray seals battlefield wounds, stops bleeding in a second

Scientists at the Korea Advanced Institute of Science and Technology (KAIST) have developed an innovative spray that can stop severe bleeding almost instantly by transforming blood into a soft, rubbery gel within a second. This spray, designed primarily for battlefield and emergency medical use, physically seals wounds and accelerates the body's natural clotting process without the need for pressure, unlike traditional bandages or tourniquets. It is particularly effective for treating gunshot wounds, shrapnel injuries, and deep or awkward cuts, and can absorb up to seven times its weight in blood. The spray’s key component, called AGCL, combines three natural ingredients: alginate from seaweed, which gels upon contact with blood; gellan gum from bacteria, which strengthens the gel to withstand pressure; and chitosan from crustacean shells, which attracts blood cells and platelets to speed clotting. While promising, the spray is still in the research phase and requires clinical trials and regulatory approval before widespread use. If successful
