Non-invasive Imaging of Spatiotemporal Ion Distribution Across Cell Membranes

Ion transport between cells and their surroundings occurs through ion channels on the cell membrane. This process can also be anisotropic, wherein ions are distributed non-uniformly around the cells. Recently, researchers have utilized electrical impedance tomography (EIT), a non-invasive technique, along with an ion transport model to detect ion channel activity. Assessment of such transport can facilitate tissue detection and drug discovery.
