Scientists from the Korea Advanced Institute of Science and Technology have developed a new spray capable of stopping severe bleeding almost instantly, in an innovation that could revolutionize emergency medicine, especially in cases where a patient's life is at risk due to blood loss, such as on battlefields. The research team stated that the spray reacts with the blood, converting it within less than a second into a soft, gel-like substance with a rubbery texture, which allows for the rapid mechanical closure of the wound, in addition to helping to accelerate the body's natural clotting process. Compared to traditional first-aid measures that rely on bandages and direct pressure on the injury site, the spray is distinguished by its speed and the fact that it does not require applying pressure to the wound—a critical factor in traumatic injuries where every second counts. The researchers also noted that the spray is suitable for injuries such as gunshot wounds, explosion shrapnel, deep or hard-to-bandage wounds, as well as cases where tourniquets or medical gauze do not work as required. They also explained that the powder can absorb an amount of blood equivalent to about seven times its own weight.
