Application
Si-substituted hydroxyapatite (Si-HAp) nanopowder can be incorporated in biodegradable polymer composites or deposited on biocompatible surfaces similar to pure HAp nanopowder (cat. no. 677418). Biological activity of HAp was shown to be enhanced by substitution of silicon ions into a fraction of HAp lattice phosphate sites.

Piperonal-catabolizing microorganisms were isolated from soil, the one (strain CT39-3) exhibiting the highest activity being identified as Burkholderia sp. The piperonal-converting enzyme involved in the initial step of piperonal metabolism was purified from strain CT39-3. Gene cloning of the enzyme

Si, Mg-substituted hydroxyapatites, alone and co-substituted, have been prepared to obtain biomaterials having an improved biocompatibility. From FT-IR, XRD and ICP analyses, it was confirmed that single phases of hydroxyapatite substituted by Si alone or co-substituted by Si, Mg. The
