Microrobots aid recovery in mice with spinal cord injuries

Microrobots aid recovery in mice with spinal cord injuries Researchers developed six-micrometre stem-cell microrobots, guided by magnetic fields, to help recover movement in mice with severed spinal cords. These microrobots transformed stem cells into neurons through wireless stimulation, eliminating the need for implanted electrodes. After 28 days, connected nerve cells improved movement in the mice, with no adverse effects noted. A similar approach in zebrafish showed quicker recovery, with near-normal swimming in just three days. These scalable microrobots can be produced on a lab-on-a-chip within thirty minutes and dissolve after use, with potential applications in areas like cardiology and wound healing. 📰 @aipost
