Hitching a ride at the nanometer scale: transport in passive and active complex media
Nikta Fakhri (Georg-August-Universität Göttingen)
Transport in crowded and complex media is a ubiquitous phenomenon in nature, which poses fundamental questions in statistical and soft matter physics. In particular, transport in the bustling interior of living cells is fascinating and far from understood. On a molecular scale, transport can be diffusive or driven, either externally or by local force generators. In this talk, I will introduce single-walled carbon nanotubes (SWNTs) as highly versatile multi-scale probes to investigate different modes of transport in media of increasing complexity: from the confined dynamics of semiflexible polymers in crowded environments to random stirring generated by non-equilibrium dynamics of the cell cytoskeleton.
