Researchers at the Greensboro Joint School of Nanoscience and Nanoengineering in North Carolina are in the process of developing a device that would use blood, saliva, or a urine sample from a person to detect if a person has sustained a head injury. A chip will sense the presence of compounds in the body that the brain releases when it's injured. The test is one that could be done quickly on the scene of an auto accident, on a ski slope, or even on a football field. Researchers hope to have a prototype of the detection device by the end of 2011. This is truly a great advancement for Traumatic Brain Injury victims, because the sooner a brain injury is detected, the more effective treatment can be for the injured victim.
