Welcome to the department of Prof. Katharina Landfester
Physical Chemistry of Polymers
We view it as our mission to create colloids with increasingly specific and complex properties for new materials and bio-medical applications and to use the confinement of stable nanodroplets to tune chemical reactions and transformation processes. Particles suspended in a liquid, known as a colloid, are versatile and flexible in their uses. They are found everywhere in our daily lives, from mother's milk to adhesives and automobile paint to the most modern technologies. The special properties of colloids can therefore be adapted in each case to the intended purpose. That facilitates the enormous versatility of the miniemulsion process. From the encapsulation of dedicated molecules, like drugs, self-healing agents etc. through to generation of extremely small nanostructures, these simple spheres can be utilised with a highly uniform size and a defined functionality of the surface. The significance of the miniemulsion technique is that it is possible to use a wide variety of polymerization techniques with a wide range of monomers. Hereby important factors like size, shape, degradation, release kinetics, surface functionalization can be precisely tuned as requested. The continual progress in knowledge about the properties of nanoscale objects and their interactions with living tissue like cells or with electromagnetic radiation opens diverse opportunities.
