๐ฉน South Korea's New Powder Seals Life-Threatening Wounds in Under One Second
Researchers at KAIST developed a spray-on powder called AGCL that turns into a rubbery gel the instant it touches blood โ in about one second flat. It's made from three natural ingredients: seaweed extract, a bacterial thickener, and chitosan from crustacean shells. The gel physically seals even deep, irregular wounds while simultaneously accelerating the body's own clotting process. Could this become standard kit in ambulances and on battlefields?
