Purpose: The purpose of this study was to enhance the lifespan of the implants applied in the osteoporosis patients through modifying the surface.Our group has successfully prepared chitosan/gelatin(CS/G)coatings on the titanium surface via electrophoretic deposition(EPD).Strontium represents a new promising candidate to prevent and treat osteoporosis.Here,we explored further to prepare CS/G coatings loaded with strontium via EPD.The physico-chemical properties of Sr/CS/G coatings were respectively observed.
