She returned to Germany, where she joined the Max Planck Institute of Colloids and Interfaces and oversaw the emulsion group.
[citation needed] Landfester joined the University of Ulm as a full professor and head of the Department of Organic Chemistry.
Whilst at the university, she started to explore materials for biomedical applications, with a focus on better understanding the interactions of nanoparticles with cellular compartments.
[3] Colloids are particles suspended in a liquid, and can permit the encapsulation of therapeutic and self-healing agents as well as the creation of specific nanostructures.
[3] She is interested in the creation of protocells – vesicular structures that are generally considered the minimal units of synthetic biology – from self-assembled block copolymers.
