Polymers are complex molecules having a reach set of topologies that affect their diffusive behavior.  Understanding how polymers diffusive has been a topic of great scientific and applied interest on a variety of fields.  As an example, a theoretical model of a polymer can as a paradigm to other long molecules, such as those commonly found in biology.

Recent research interest has shifted from bulk studies, where there is more complete understanding to studies on surfaces. I will present some recent work based of polymer diffusion on more realistic cases, including preliminary results for bioapplications.
