We study the properties of diblock copolymer based membranes by means of single-molecule detection. The membranes are prepared by the phase inversion method and the structural details like morphology, film thickness and pore sizes are known from scanning electron microscopy.
Tracking the spatial position of individual water soluble perylene molecules allows us to follow the diffusion through the membrane.
