Magnetically-directed nanoparticles could help heal broken bones

http://ift.tt/1AKMrsd

When a bone is severely broken in the human body, or a bone-fused prosthesis is implanted, a bone graft is also often required to ensure a solid mechanical repair. However, a graft that removes bone from another area of the body can be a painful and invasive procedure, and the mechanical stimulation required for continued bone regeneration in post-operative therapy becomes problematic if a patient is severely immobilized. To address these problems, researchers have discovered that coating magnetic nanoparticles with proteins and then directing them magnetically to the site of the injury can help stimulate stem cells to regenerate bone...
