Strontium (Sr) Doped Calcium Phosphate Coatings on Biodegradable Magnesium Alloys

摘要

Pretreatment conditions and Sr concentration were found to greatly influence the vol. % of crystalline content in CaP coatings and their capability to provide corrosion control. Greater levels of osteogenic differentiation were observed on coatings prepared with increased amounts of Sr regardless of pretreatment conditions. Future studies will aim to incorporate Sr doped CaP nanoparticles into polymeric coatings to control the release of Sr and bioactive molecules to further improve the bioactivity of metallic implants.
