Abstract

A microporous film of silicon is shown to induce hydroxyapatite growth both on itself and on neighboring areas of bulk silicon (e.g. see figure). This indicates that silicon could be developed as an active biomaterial, which has encouraging implications for the use of VLSI technology in, for example, invasive sensing and biosensing and other electronic prosthetic devices
