Scientists Develop Powder for Emergency Control of Severe Bleeding

🧫 Scientists from the Korea Institute of Science and Technology have developed AGCL powder for rapid control of severe bleeding.
🩸 What Is AGCL Powder?
Scientists from the Korea Institute of Science and Technology (KIST) have developed AGCL powder — a novel hemostatic agent for emergency control of severe bleeding. In preclinical studies, it significantly reduced blood loss and accelerated hemostasis compared to TachoSil, one of the clinical standards for bleeding control.
Upon contact with blood, the powder reacts with calcium ions and transforms into a dense hydrogel within seconds, physically sealing the wound.
⚡
Rapid Action Seals wounds in seconds
🩸
High Absorption 7x its weight in blood
🛡️
Antimicrobial >99.9% bacterial reduction
💡 Key Innovation: The powder is suitable for deep, large, and irregular wounds — unlike conventional bandages that are limited to flat, accessible surfaces.
⚙️ How the Technology Works
🧪
1. Contact with Blood
AGCL powder reacts with calcium ions present in blood upon application to the wound.
💧
2. Hydrogel Formation
Transforms into a dense hydrogel within seconds, physically sealing the wound and stopping blood flow.
🩸
3. Blood Absorption
Absorbs up to 7 times its own weight in blood while maintaining a secure seal on the tissue.
📊 Key Research Findings
7x
Blood Absorption Absorbs nearly 7 times its own weight in blood
99.9%
Bacterial Reduction Reduces viable bacteria by more than 99.9%
24
Months Stability Maintains properties during storage for up to 24 months
💡 Safety Profile: The powder showed minimal damage to red blood cells, exhibited no cell toxicity, and accelerated tissue regeneration, new blood vessel formation, and collagen synthesis.
📊 AGCL vs TachoSil — Comparison
| Parameter | AGCL Powder | TachoSil (Standard) |
|---|---|---|
| Hemostatic Speed | Faster | Standard |
| Blood Loss Reduction | Superior | Standard |
| Wound Suitability | Deep, large, irregular | Flat, accessible |
| Antibacterial Effect | >99.9% | Limited |
| Tissue Regeneration | Enhanced | Standard |
🏥 Potential Applications
Following further trials, the technology could be applied in:
🏥
Surgery Intraoperative bleeding control
🚑
Emergency Medicine Trauma and accident response
⛑️
Disaster Response Field and mass casualty situations
⚔️
Military Medicine Combat casualty care
❓ Frequently Asked Questions
