The use of magnetic hydrogel as a minimally invasive treatment for sciatic nerve repair. A magnetic hydrogel is synthesized by uniformly dispersing magnetic nanoparticles through a hydrogel. The magnetic hydrogel is then injected into a rat with a damaged sciatic nerve. The magnetic hydrogel is stimulated with an external magnetic field. The magnetic stimulation induces directionally oriented axonal growth, leading to sciatic nerve regeneration and recovery. The sciatic nerve is healed with natural degradation of magnetic hydrogel within the body
