A variety of metal ions and complex ions exist in living organisms and are involved in various biological processes. In addition to physiological and molecular biological methods, quantitative research from the viewpoint of material science is important to understand the mechanism of their uptake from the exterior environment and their function in the body. We focused on the contribution of diffusion to the mechanism of iron uptake via the iron scavenger mugineic acid in grasses: studied the interfacial properties of polyprotic iron complexes, the effect of coexisting ions, and the pH dependence of the interaction between iron complexes and membranes using model–independent interfacial thermodynamics.
