Abstract
Bioactive silicon comprising a porous form of silicon which when in vivo elicits a specific biological response that results in the formation of a bond between living tissue and the silicon. The deposition of apatite provides an indication that the porous silicon is bioactive and therefore biocompatible. Bioactive silicon may be used in the fabrication of biosensors for in vitro or in vivo applications.
