Interfacial effects on single dye dynamics in ultrathin liquid films and in nanopores — •Fabian Meier, Daniela Täuber, and Christian von Borczyskowski — nanoMA, TU-Chemnitz, Institut für Physik

Nanopores have gained importance as filters in industrial and environmental applications. Thereby interactions of guest molecules are of interest, and thus have led to ongoing research. Here we use single molecule methods to explore the dynamics of dye molecules within nanopores and ultrathin liquid films [1,2] on differently treated silica surfaces. In contrast to ensemble methods, we thereby gain information on a local sub-micron scale. This allows us to draw conclusions on diffusion coefficients and physio-chemical binding affinities depending on the chemical structure of participating molecules and solid surfaces.
