Mission
Biomimetic material research focuses on the identification of structural features of biological specimen that are responsible for remarkable material properties and on the replication of these relevant micro- and nanostructural features into manmade materials. Our research concentrates on the engineering of meso- and microscaled structures from softmatter materials. The structures are prepared by lithographic technologies (Softlithography, E-beam lithography and 2-Photon lithography) or by controlled self-assembly processes. The fundamental understanding of self-organization processes in confined microenvironment is a requirement for the combination of top-down based microstructure technologies and bottom up based strategies for mimicking biological structures in synthetic materials.
