Surface functionalisation of magnesium alloys for use as bio-implants

Magnesium-based alloys containing appropriate quantities of Strontium can induce optimal bone formation. Surface modification of these alloys with Collagen-I increased mineral deposition on the peri-implant surface over shorter periods of time as compared to the unmodified alloys, indicating the role of Collagen-I and Strontium concentration in bone resorption and remodelling.
