Nanoparticle Offers Early-Stage Treatment to Brain Injuries
Researchers at Rice University are reporting success in using a nanoparticle as an emergency treatment for traumatic brain injuries. The research could also improve brain injury treatment for stroke victims and organ transplant patients.
The nanoparticle, which was developed at Rice University, is polyethylene glycol-hydrophilic carbon clusters (PEG-HCC). It's already being tested in cancer treatment, where it has shown itself to be a powerful antioxidant.
In the current research, the Rice team took PEG-HCC's effectiveness as an antioxidant one step further, by using it to counter something called reactive oxygen species (ROS)—after a traumatic brain injury, cells release an excessive amount of an ROS called superoxide (SO) into the blood.
