Affinity of several bio-trace elements to various reconstructed lipid membranes (liposomes) was assessed using multitracer analysis technique (MTAT). To estimate affinity of bio-trace elements to the sub-cellular components such as lipid membranes, MTAT was applied to the various reconstructed liposomes. Phosphatidylcholine and sphingomyelin liposomes showed a similar pattern of elemental affinity. Phosphatidylserine, phosphatidylglycerol, and phosphatidylinositol liposomes showed another similar pattern of elemental affinity, except that phosphatidylinositol liposome has no affinity to vanadium.
