KAIST has developed 'AGCL Powder,' a hemostatic agent that forms a hydrogel barrier within one second when applied to wounds. The powder is a blend of biocompatible materials like alginate and chitosan, reacting with blood cations to seal wounds instantly.

It can absorb over 725% of its weight in blood and withstands pressures exceeding 40kPa. With a hemolysis rate below 3% and an antibacterial effect of 99.9%, it shows promising tissue regeneration capabilities.

The powder maintains efficacy for two years under various conditions, making it suitable for military operations and disaster response. Developed with input from Army major Park Gyu-soon, the technology aims to minimize casualties in combat and can also be used in emergency medical situations, extending its application from the battlefield to civilian medical care.
