Real‐time ion flux imaging: an ion‐sensitive field‐effect transistor (ISFET) array is coupled with optical microscopy to image the growth of, and ion flux through, micrometer‐scale tubes and membranes built from polyoxometalate clusters. The correlation between the optical and ionic imaging data is excellent, showcasing the use of ISFET arrays for high‐resolution spatial and temporal mapping of ionic movements.
