Artificial platelets could treat injured soldiers on the battlefield
When it comes to healing the terrible wounds of war, success may hinge on the first blood clot – the one that begins forming on the battlefield right after an injury.
Researchers exploring the complex stream of cellular signals produced by the body in response to a traumatic injury believe the initial response – formation of a blood clot – may control subsequent healing. Using that information, they're developing new biomaterials, including artificial blood platelets laced with regulatory chemicals that could be included in an injector device the size of an iPhone. Soldiers wounded in action could use the device to treat themselves, helping control bleeding, stabilizing the injury and setting the right course for healing. [More…]
