Nano-scaffolding (or nanoscaffolding) is a medical process used to regrow tissue and bone, including limbs and organs. Developed by the American military, the medical technology uses a microscopic apparatus made of fine polymer fibers called a scaffold.[1] Damaged cells grip to the scaffold and begin to rebuild missing bone and tissue through tiny holes in the scaffold. As tissue grows, the scaffold is absorbed into the body and disappears completely.
Nano-scaffolding has also been used to regrow burned skin. The process cannot grow complex organs like hearts.[2]
