Abstract
AbstractSurface‐charge measurements of mammalian cells in terms of Zeta potential are demonstrated as a useful biological characteristic in identifying cellular interactions with specific nanomaterials. A theoretical model of the changes in Zeta potential of cells after incubation with nanoparticles is established to predict the possible patterns of Zeta‐potential change to reveal the binding and internalization effects. The experimental results show a distinct pattern of Zeta‐potential change that allows the discrimination of human normal breast epithelial cells (MCF‐10A) from human cancer breast epithelial cells (MCF‐7) when the cells are incubated with dextran coated iron oxide nanoparticles that contain tumor‐homing F3 peptides, where the tumor‐homing F3 peptide specifically bound to nucleolin receptors that are overexpressed in cancer breast cells.
