Nerve Regeneration, Nanoscale Scaffold

An interesting article from the BBC examines what seems to be a way to produce self-assembling scaffolds for nerve regeneration: "The researchers injected the blind hamsters at the site of their injury with a solution containing synthetically made peptides - miniscule molecules measuring just five nanometres long. Once inside the hamster's brain, the peptides spontaneously arranged into a scaffold-like criss-cross of nanofibres, which bridged the gap between the severed nerves. The scientists discovered that brain tissue in the hamsters knitted together across the molecular scaffold, while also preventing scar tissue from forming. Importantly, the newly formed brain tissue enabled the brain nerves to re-grow, restoring vision in the injured hamsters."
