Scientists in South Korea have developed an effective medical powder that stops bleeding in just one second, marking a major scientific breakthrough.
Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a new medical technology in which a special powder, when sprinkled on a wound, forms a strong protective hydrogel layer within one second, instantly stopping heavy bleeding.
This discovery is of particular importance in war zones, accidents, and emergency medical situations. The new material is called AGCL Powder and has been created through joint research in the fields of engineering and biological sciences.
The working mechanism of the powder is such that when it comes into contact with blood, it reacts with calcium ions present in the blood and transforms into a hydrogel within about one second. This transformation tightly seals the wound and stops the flow of blood.
The powder is a blend of natural and biologically safe materials such as alginate, gellan gum, and chitosan. Its three dimensional structure can absorb more than seven times its own weight in blood, making it effective even in cases of severe bleeding. Its adhesive strength exceeds 40 kPa, allowing the wound to remain firmly sealed even under high pressure.
Experiments conducted on animals showed that the powder reduces bleeding time and delivers better results than commonly used hemostatic products. With its use, the rate of blood cell rupture remains below 3 percent, cell viability exceeds 99 percent, and it is 99.9 percent effective against bacteria.
The powder remains effective for up to two years when stored at normal temperature and humidity, making it ideal for immediate use in battlefields, disaster zones, or areas with limited medical facilities. Although the research initially began for defense purposes, researchers say the technology could also prove highly useful in emergency medicine, surgery, and humanitarian aid. A Korean military officer was also involved in the project.
The findings of this research have been published in the international journal Advanced Functional Materials. This new barrier forming powder technology has proven to be much faster, stronger, and safer than most traditional medical products, opening the door to major advancements in first aid and complex surgical procedures in the future.
