The coated magnetic nanoparticle method used by medical researchers from Keele and Nottingham universities in the UK, however, is claimed to be able to direct materials straight to an injury site without the need for surgery. It is then possible to remotely manipulate the nanoparticles to produce mechanical forces and maintain the bone regeneration process through the delivery of stem cells and a staged release of a growth stimulating protein. It's going to replace our old techniques of healing broken bones which requires a surgery and gives a lot of pain !!
