The research team at the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon, which included an Army Major, created the powder that rapidly forms a strong hydrogel barrier when sprayed directly onto a bullet wound. Also, current powders that stop blood flow have limited functionality by physically absorbing blood to form a barrier, according to the study published in the journal Advanced Functional Materials. “The new AGCL powder reacts with cations, such as calcium in the blood, to turn into a gel state in one second, instantly sealing the wound,” said study co-leader Professor Steve Park.
