3D-printed guide helps regenerate complex nerves


Key points from article :

Regrowth of nerves after injury or disease is very rare.

New technique 3D imaged and 3D printed a custom silicone guide with biomimetic physical cues (microgrooves) and path-specific biochemical cues.

Successfully tested on rat’s sciatic nerve.

Don’t have to worry whether the drugs will work and be safe in humans, but won’t have original 3D scan after an accident so use library of standard nerves instead.

The study was published in the Advanced Functional Materials journal.
