Bioidentical, dissolvable brain implants for monitoring injury

click to enlargeA pressure and temperature sensor which sits on the surface of the brain to monitor intracranial pressure and temperature changes has been developed by an international team from South Korea and the US. Currently, implantable sensors are used for monitoring victims of severe traumatic brain injury (TBI), but these sensors carry risk of inflammation and infection. In initial testing, this new sensor has been found to be fully biocompatible (no inflammation or scarring) and dissolves in a few weeks. It can also be modified in other ways to monitor other brain functions, such as acidity and the motion of fluids, or deliver drugs. Published in Nature. Summary in the Guardian.
