The time response of an ion-sensitive dye can be affected by the permeability of the carrier system. The time response of seminaphtharhodafl uor (SNARF) entrapped in polyelectrolyte multilayer capsules can be calculated in a microfl uidic channel with a time-dependent pH concentration profi le via magnetic trapping and fl uorescent microscopy. Moreover, the ion conductivity of polyelectrolyte multilayer fi lms functionalized with nanoparticles can be calculated by the technique bombardment induced ion transport (BIIT).
