We describe different types of bioceramic nanoparticles and their application for drug delivery and tissue engineering. We then discuss the major challenges in tissue engineering and the ways to overcome them with the help of nanomaterials. Nanomaterials are designed so that to biomolecules can easily be attached to their surface, which can then be transferred into cells. They can also act as controlled release systems, which carry growth factors or cytokines, and support tissue morphogenesis, viability and functionality. The main characteristics of optimal nanoparticulate carriers are presented.
