A new class of synthetic platelet-like particles could augment natural blood clotting for the emergency treatment of traumatic injuries – and potentially offer doctors a new option for curbing surgical bleeding and addressing certain blood clotting disorders without the need for transfusions of natural platelets.
The clotting particles, which are based on soft and deformable hydrogel materials, are triggered by the same factor that initiates the body’s own clotting processes. Testing done in animal models and in a simulated circulatory system suggest that the particles are effective at slowing bleeding and can safely circulate in the bloodstream. The particles have been tested with human blood, but have not undergone clinical trials in humans. Via Platelet-Like Particles Augment Natural Blood Clotting for Treating Trauma
