Microrobots Repair Spinal Cord
ETH Zurich researchers have developed 'NPCbots,' biohybrid microrobots that combine stem cells with magnetoelectric nanoparticles to repair spinal cord injuries. These robots can be guided magnetically to injury sites to stimulate nerve cell regrowth.
Why it matters
This innovation offers a potentially more effective and less invasive method for treating spinal cord injuries compared to traditional implanted electrodes.
Spinal cord injuries can have devastating consequences for those affected. Nerve cells in the spinal cord rarely regenerate naturally, while scarring often prevents the regrowth of nerve fibres. Modern therapies attempt to influence implanted stem cells using electrical stimulation to promote the growth of new nerve cells. This approach has several drawbacks: it requires implanted electrodes, and the transplanted cells do not always survive or integrate properly into the existing tissue.
