[A review of research progress on biological effects about nanometer scaffold for bone tissue engineering]

Quite a few orthopedics experts have fabricated some novel bone scaffolds with nanotechnology and have carried out some researches on nano-biological effects. The study of the biological effects about nano-biomaterials can facilitate the understanding of the interaction between the biomaterials and the organism, and provide research ideas and direction to construct new biomaterials with physiological function. To better understand the interaction of nano biomaterials with protein, cells and bio-security, this review presents recent advances of biological effects about nano scaffold for bone tissue engineering.
