The ideal bone scaffold harnesses the body's ability to regenerate bone in critical size defects. A potential strategy to design the ideal bone scaffold is to mimic the natural structure of bone at the molecular level. The orientation and spatial distribution of nanocrystals in the organic matrix are two important and distinctive structural characteristics(More)
