Seoul, Jan. 27 (SANA) Scientists in South Korea have developed a sprayable powder that can stop severe bleeding in about one second by sealing deep wounds on contact with blood, officials said. The technology is designed for emergency and field medicine, offering a rapid solution for serious injuries in situations with limited time or resources.
Bleeding is a leading preventable cause of death worldwide, particularly in accidents, natural disasters, and combat scenarios where immediate surgical care is unavailable. Researchers at the Korea Advanced Institute of Science and Technology, in collaboration with the South Korean military, developed the powder as a faster and more effective alternative to conventional bandages.
According to My Modern Met, the powder hardens instantly when it touches blood, forming a protective layer. It is effective in challenging conditions where gauze or manual pressure is difficult to apply. When sprayed onto a wound, the substance spreads evenly and solidifies into a strong hydrogel barrier that adheres to tissue, allowing deep and irregular wounds to be sealed without sutures or prolonged pressure.
Preclinical tests indicate the powder can reduce bleeding time and promote tissue regeneration. While it has not yet received approval for widespread clinical use, the innovation is being hailed as a potential breakthrough in emergency care and trauma medicine.
