DNA-Functionalized Colloids
Self-Assembly and Aggregation
Developing New Materials

Erika Eiser


My group focuses on developing NEW MATERIALS using self-assembly and contolled aggregation processes. In particular we use the high specificity of DNA, end-grafted to colloids, to design well-defined porous gels, which we aim to develop into photonic and potential battery materials. Further we are interested in protein aggregation - another porous material relevant for understanding diseases but also useful as new material in drug delivery and food industry.
Our interdisciplinary research combines experimental physics, physical chemistry, and biochemistry, as well as simulations. Many of our projects are in colaboration with various international groups.
