A UCF team created a liquid gel that transforms into a spongelike antimicrobial foam to impede severe bleeding. SilFoam’s porousness and adhesion properties help it expand and seal a wound, allowing the body’s natural clotting process to take over, says Kausik Mukhopadhyay.
The sponge applies pressure to restrict the hemorrhage while its silver oxide component serves as an antibacterial agent. The sponge also results in gentler removal. “The adhesive property of this bandage is optimized so that when you take it out from the system, the smaller vessels don’t get ruptured.” SilFoam’s advantages over other methods include less leakage, room-temperature storage, and lower costs.
