can be accomplished by a new material that acts as a scaffold for the human
body to repair bones with chips missing. This material,
poly(lactide-co-glycolide), is placed in living bones, which allows the
osteoprogenitor cells, the cells that build bones, to attach to the
scaffold. The cells also release enzymes that break down the scaffolding.
This allows the bone being built to completely replace the compound.

Medicine is one of many
fields incorporating nanotechnology. Current usage today
can be seen in nanostructured materials identical in composition to bone for
orthopedic use. One area of current research focuses on nanofiber
based tissue engineering. Nanofiber scaffolds would be used to support
stem cell growth outside the body for cardiovascular tissue grafts and hard
tissue grafts inside the body.
