‘Knit’ severed spinal cords with graphene ribbons

December 30, 2016

A new material made of graphene nanoribbons and a common polymer might help knit damaged or even severed spinal cords. 

 

The nanoribbons are highly soluble in polyethylene glycol (PEG), a biocompatible polymer gel used in surgeries, pharmaceutical products, and in other biological applications. When the nanoribbons have their edges functionalized with PEG chains and are then further mixed with PEG, they form an electrically active network that helps the severed ends of a spinal cord reconnect.
