Effect of Mg composition on in vitro biomineralization. EDS elemental analysis of the PLGA and PLGA-Mg composites after 14 day immersion in 1.5× SBF. The presence of Ca (outlined in white and overlaid in other groups) and P groups were detected in the nucleates for both polymer and composite groups, indicating formation of calcium apatite. The precipitation of calcium apatite coincided with the presence of Mg in the PLGA-Mg composite films, indicating a relationship between the increased local Mg concentration and the calcium apatite nucleation and growth.
