The bioactivity of a range of microstructured silicon materials should be assessed since it has been demonstrated that low porosity microporous silicon is “bioactive”. Work reported here shows that certain types of polycrystalline silicon are also bioactive, being corroded and exhibiting surface deposits of calcium phosphate (see Figure) when kept in simulated body fluids (SBF).
