Nano‐ to Microscale Porous Silicon as a Cell Interface for Bone‐Tissue Engineering

Abstract

Porous Si (PSi) is shown to support and promote primary osteoblast growth (shown in the figure), protein-matrix synthesis, and mineralization. It is also shown that the osteoconductivity of PSi and other cellular responses can be controlled by altering the micro-/ nanoarchitecture of the porous interface. This material has the potential to be a functional biomaterial with both osteoconductivity and drug- delivery functions.
