The method of single particle orbit tracking (SPOT) permits to record the trajectories of fluorescent particles in three dimensions for long observation times (up to tens of minutes) [1,2]. This versatile technique can be applied in the field of life sciences as well as in the materials chemistry. We want to investigate the diffusion behavior of tracer particles within different block copolymer membranes with a stimuli-responsive block covering the pore surface [2]. Our aim is to adress changes in the trans-membrane and intra-membrane transport parameters as a function of the particle properties or variations of the environmental conditions.
