Knitting Severed Spinal Cords With Graphene Ribbons

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…Continue readingKnitting Severed Spinal Cords With Graphene Ribbons

Graphene-Based Interfaces Do Not Alter Target Nerve Cells

Researchers have successfully demonstrated how it is possible to interface graphene – a two-dimensional form of carbon – with neurons, or nerve cells, while maintaining the integrity of these vital cells. The work may be used to build graphene-based electrodes that can safely be implanted in the brain, offering promise…Continue readingGraphene-Based Interfaces Do Not Alter Target Nerve Cells
