In emergency rooms, trauma centers, and across the medical field, one of the constant enemies for nurses, doctors, and surgeons is time. Uncontrolled bleeding is the number one cause of preventable death from trauma. Severe blood loss can lead to death in a matter of minutes, but even with the advancements in modern medicine, there was far from enough forward movement in finding a resolution. That is, until a research team of scientists, including one active duty Army Major, just recently pulled off something that sounds like it’d be straight out of a movie. In a historic development, the research team created a new method that’s reportedly capable of stopping bleeding in just one second—literally.
The 1-Second Miracle: A New Way to Stop Bleeding Almost Immediately
The creation of this new approach to stopping bleeding has unparalleled potential if moved forward in the medical industry, and could save countless lives in the process. As SciTechDaily first reported, scientists from KAIST (Korea Advanced Institute of Science and Technology), widely regarded as South Korea’s premier science and technology university, are behind the creation of a unique spray made to improve survival in combat and emergency medicine.
According to the report, the team created a “fast-acting, stable powder hemostat that stops bleeding in one second.”
The news first surfaced in an announcement from KAIST in late December 2025, revealing that a joint team led by Professor Steve Park of the Department of Materials Science and Engineering and Professor Sangyong Jon of the Department of Biological Sciences created the powder. The spray quickly forms a strong hydrogel barrier, and when applied to the wound, it transforms and hardens within roughly one second to seal the injury.
How the Newly Created Powder-Based Product Combats Blood Loss
The entire research article can be found on Wiley Advanced and includes a detailed breakdown of all aspects of the work behind the potentially game-changing product. The research features several interesting data graphics, including a thorough look at how the powder turns into a hydrogel to combat bleeding almost immediately.
Here’s a breakdown of a few of the details behind how the stable powder hemostat reportedly works:
- When sprayed onto an open wound, the powder-based hemostatic agent almost immediately seals off any blood loss by hardening over the area.
- It creates a hydrogel barrier in roughly one second, immediately stopping blood loss and preventing it from continuing.
- The unique powder-turned-hydrogel reportedly works as intended even in harsh environments and conditions.
- According to the details released, it also remains stable during storage, allowing it to be quickly applied in potential emergencies, as SciTechDaily explained.
- The site explains that other “patch-type hemostatic products” struggle to treat deep wounds due to their flat shape and sensitivity to heat. This led to KAIST targeting a method capable of overcoming these issues.
- The product can reportedly absorb blood more than seven times its own weight, including excessive bleeding.
KAIST’s research team created the product in a form that can reportedly be used on various-sized injuries, including deep or uneven wounds. It was tested in surgical liver injury experiments, and the results highlighted significant success in reducing bleeding. The report also reveals that liver function returned to normal levels two weeks after surgery, with no abnormal findings.
It’s an incredible creation by all those involved from KAIST, and one that could have a significant impact on helping to combat excessive blood loss at an unbelievable speed.
