Nanoparticles Used To Deliver Treatment For Brain, Spinal Cord Injuries

ScienceDaily (Oct. 2, 2008) — Purdue University researchers have developed a method of using nanoparticles to deliver treatments to injured brain and spinal cord cells.

A team led by Richard Borgens of the School of Veterinary Medicine's Center for Paralysis Research and Welden School of Biomedical Engineering coated silica nanoparticles with a polymer to target and repair injured guinea pig spinal cords. That research is being published in the October edition of the journal Small.

The team then used the coated nanoparticles to deliver both the polymer and hydralazine to cells with secondary damage from a naturally produced toxin. That research was published in August by the journal Nanomedicine.
