A soldier is badly wounded on the battlefield in Afghanistan or Iraq by a roadside explosive. As he lies beside his vehicle, unable to reach his radio to contact his unit on his location and condition, blood from the wound seeps into his shirt. Luckily, its fibers are coated with cylindrical, nanosize carbon molecules that contain antibodies able to detect the presence of albumin, a protein common in blood. The shirt senses that its wearer is bleeding and sends a signal through the shirt's carbon nanotubes (1,000 times more conductive than copper) that activates an emergency radio-frequency beacon on the soldier's belt. This distress call is picked up by a nearby patrol that rushes to the aid of their wounded comrade. [More]
