Urgent: One Second to Save a Life – New Powder Instantly Stops Bleeding, Developed with Military Input
SEOUL, SOUTH KOREA – October 29, 2024 – In a stunning breakthrough poised to redefine trauma care, researchers at the Korea Advanced Institute of Science and Technology (KAIST) have unveiled a next-generation powder hemostatic agent capable of halting severe bleeding in as little as one second. This isn’t just incremental improvement; it’s a paradigm shift, particularly for battlefield medicine and disaster response, and a major win for Google News indexing.
The Problem with Bleeding: A Race Against Time
Excessive blood loss remains a leading cause of death in traumatic injuries, especially in conflict zones and during natural disasters. Traditional hemostatic methods – bandages, patches, and even existing powders – often struggle with deep wounds, irregular shapes, and challenging environmental conditions. They can be slow to act, difficult to apply effectively, and susceptible to temperature and humidity. The stakes are impossibly high; every second counts.
AGCL Powder: A Revolutionary Approach to Hemostasis
The KAIST team, notably including Army Major Gyu-sun Park, tackled these limitations head-on. Their solution: AGCL powder, a biocompatible formulation combining alginate, gellan gum, and chitosan. Unlike previous powders that simply absorbed blood, AGCL leverages the power of ion reactions. When sprayed onto a wound, it reacts with calcium and other positive ions in the blood, instantly transforming into a robust, gel-like barrier. This isn’t just absorption; it’s rapid, chemical sealing.
“The core of modern warfare is minimizing human loss,” explains Major Park, whose dedication stemmed from a “sense of mission to save at least one more soldier.” His direct involvement ensured the technology’s practicality in real-world combat scenarios.
Beyond Speed: Absorption, Strength, and Safety
The AGCL powder doesn’t just stop bleeding quickly; it does so effectively. It can absorb up to 725% of its own weight in blood, providing a powerful seal even under high pressure. Testing reveals an adhesive strength exceeding 40kPa – enough to withstand significant manual pressure. Crucially, the powder is entirely composed of natural substances, demonstrating exceptional safety: hemolysis rates below 3%, cell survival rates over 99%, and a 99.9% antibacterial effect. Animal studies have also shown promising tissue regeneration, accelerating wound healing and promoting blood vessel growth.
From Battlefield to Operating Room: Versatility and Stability
The powder’s versatility extends beyond the battlefield. Its sprayable form allows for application to complex and irregular wounds, a significant advantage over traditional patch-type hemostatic agents. Furthermore, AGCL maintains its effectiveness for up to two years even in challenging conditions – high humidity and room temperature – making it ideal for deployment in disaster zones, developing countries, and remote medical settings. This represents a significant leap forward in accessibility to life-saving trauma care.
A Spin-Off Success: Defense Technology Serving Civilian Needs
This innovation isn’t just a military advancement; it’s a prime example of “spin-off” technology – the successful translation of defense science into civilian applications. The KAIST team’s work has already garnered recognition, winning the 2025 KAIST Q-Day President’s Award and the 2024 KAIST–KNDU National Defense Academic Conference’s Minister of National Defense Award. The potential applications are vast, ranging from emergency medical services to surgical procedures, offering a new standard in hemostasis.
The research, published in the prestigious journal Advanced Functional Materials, marks a pivotal moment in trauma care. It’s a testament to the power of collaborative research, driven by a clear mission: to save lives.
