Nanobots and spinal cords. It does not sound like a question of what could go wrong, but more a question of what could go right
Researchers have created biohybrid microrobots (sometimes described as nanobots) that combine stem-cell-derived neural cells with magnetic nanoparticles. These tiny systems can be guided and stimulated using magnetic fields to encourage nerve regeneration. In early experiments, the technology helped repair spinal cord injuries in animal models, including improved movement in zebrafish and mice
