Figure 3. — The pH-dependent interfacial equilibria of a carboxylated SPION sample (PAM@MNP) in comparison with that of naked MNP and its coating agent (PAM containing 0.4 mmol COOH). The net proton surface excess related to the unit mass of SPIONs (calculated from the material balance of H⁺/OH⁻ in the course of equilibrium acid–base titration) is proportional to the amount of surface charges developed in the interfacial layer (a). Zeta potential proportional to the particle charge at shear plane and aggregation of PAM-coated SPION sample (DLS sizes reflect the given kinetic state measured 2 min after sonication) as a function of pH and a photo of pH-adjusted series taken an hour after sonication (b).
