Rensselaer inventors created a nanocomposite fiber that promotes quick coagulation during hemorrhage resulting in reduced mobility and improved survival. The nanofiber composite is comprised of halloysite nanoclay, a natural occurring aluminosilicate nanoclay that exhibits a hollow tubular scroll structure. Hemostatic products on the market are effective in the short-term but might lack the ability to provide prolonged clotting activity. The disclosed technology overcomes these limitations as the nanoclay is physically imbedded onto the surface of the nanofibers. This not only protects against leaching, but also provides a sufficient skin to fiber interface. Preliminary data suggests it can speed clotting time over certain products on the market with the potential to improving long-term clotting.
