Researchers at KAIST have created a spray-on powder that can stop severe bleeding in about one second. This innovation could save lives on battlefields and in emergency situations.

Excessive blood loss is the leading cause of death from combat injuries. To address this challenge, researchers at KAIST developed a next-generation spray-on powder called AGCL powder. This powder can stop severe bleeding in just one second.

The research team, led by Professor Steve Park and Professor Sangyong Jon, created a powder that quickly transforms into a strong hydrogel barrier when sprayed onto a wound. The powder is designed to work with deep, irregular, or complex wounds, making it more versatile than traditional alternatives.

AGCL powder combines several naturally derived ingredients, including Alginate and Gellan Gum, which react with calcium in blood to form an ultra-fast gel. This gel rapidly seals the wound, allowing for quick bleeding control even during heavy bleeding. Laboratory testing showed that AGCL powder is safe when it comes into contact with blood, with a hemolysis rate below 3% and cell viability above 99%.

The researchers believe that this technology could have wide-ranging applications in emergency medicine, including disaster response, healthcare in developing countries, and treatment in medically underserved regions.
