Researchers at the Korea Advanced Institute of Science and Technology, in partnership with the South Korean military, have developed a spray-on powder for emergencies that can seal even severe wounds in about one second. Released from an aerosol canister, the powder spreads quickly and evenly over a wound and in contact with blood, transforms into a tough, gel-like barrier that seals the injury. The structure can absorb over seven times its weight in blood, staying intact even in high temperatures and humid conditions. In preclinical testing, the powder was used successfully on complex injuries, including liver wounds. Bleeding stopped rapidly, and the treated tissue showed signs of healthy regeneration, including formation of new blood vessels and collagen. If approved for clinical use, AGCL could become a standard tool for paramedics, military personnel, emergency rooms, and remote healthcare workers, particularly in regions where surgical care may not be immediately available.
