Scientists Develop Spray-On Powder to Stop Bleeding Instantly
Scientists at KAIST have created a special powder called AGCL that can stop bleeding very quickly, in just about one second.
This powder is made from natural materials like Alginate, Gellan Gum, and Chitosan.
When it touches blood, it turns into a gel and seals the wound.
It's safe to use and has been tested successfully on liver injuries, showing it can reduce blood loss and help healing.
The powder is designed to work well in tough places like battlefields or disaster areas, where quick and reliable treatment is needed.
The team hopes this technology will save lives in both military and medical settings.
KAIST researchers developed a powder-based hemostatic agent (AGCL powder) that stops bleeding in about one second.
The agent is made from natural materials including Alginate, Gellan Gum, and Chitosan.
It forms a strong hydrogel barrier when applied to a wound, sealing it instantly.
The technology is designed for use in extreme environments like battlefields and disaster sites.
Tests showed the AGCL powder is safe, with a hemolysis rate below 3%, cell viability above 99%, and antibacterial effectiveness of 99.9%.
