Microstructures in Biomaterials and Chemistry

Focus of Research

Bioinspired 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 and on the investigation of self organizing prozesses. Special focus is on the fundamental understanding of self-organization processes in confined microenvironment and interfaces.  We see  the combination of top-down based micro- and nanostructure technologies and bottom up based molecular assembly strategies as a fundamental approach for mimicking biological structures in synthetic materials.

The micro- and nanotechnological techniques used include:

  • 2 Photon Lithography
  • Electron Beam Lithography
  • Softlithography / PRINT

Systems involved in Self Organization studies include:

  • Oligopeptide gelators
  • Biofunctionalized magnetically controlled micro- and nanostructures
  • Interfacial assemblies at liquid/liquid, liquid/gas or liquid/solid interfaces

Properties of micro-/ meso- or nanoscopic systems involved include:

  • Wettability of chemical and topographical heterogeneous structures
