Exploring the effects of organic molecules on the degradation of magnesium under cell culture conditions

Several typical organic components, l -ascorbic acid ( l -AA), l -glutamine ( l -Gln), l -alanyl- l -glutamine ( l -Ala- l -Gln) and fetal bovine serum (FBS) were chosen to elucidate the effects of organic components on the degradation of pure Mg under cell culture conditions. The results revealed that the influence of organic components on the degradation of pure Mg is time-dependent and they play an important role in the formation of the degradation layer. The addition of organic components favors the precipitation of nesquehonite rather than hydromagnesite in the “outer” layer, while in the “inner” layer the organic components accelerates the formation of phosphate (Mg-PO4, Ca-P salts) during immersion.
