Short Bio

Prof. Lahann is currently a tenured Professor in the department of Chemical Engineering, Materials Science and Engineering, Biomedical Engineering and Macromolecular Science and Engineering at the University of Michigan (Uof M) in USA, and also the co-director of Institute of Functional Interfaces at Karlsruhe Institute of Technology in Germany.  He received his Ph.D. degree from RWTH Aachen University in 1998, and worked as a postdoc fellow under Prof. Bob Langer in MIT from 1999-2003. He has published many highly cited papers including the switchable surface in Science, the biphasic Janus particles in Nature Materials, and the engineered biointerface for stem cell study in Nature Biotech.  His research interest has focus on multifunctional particles, biomimetic materials, biointerface engineering, nano-scale self-assembly.

Engineered biointerfaces:
From switchable surfaces to multicompartmental particles

Abstract
Our improved understanding of molecular biology, microfabrication, and materials chemistry has stimulated crossfertilization of chemistry, biotechnology and materials engineering. In my presentation, I will discuss current advances in the design of multifunctional biomaterials including two distinct examples under research in the Lahann group: (i) Bicompartmental particles that exhibit a wide range of sizes, shapes and compartmentalizations have been prepared using electrified co-jetting [1,2]. The individual phases can be independently loaded with different biomolecules or selectively surface-modified. Appropriate design of compartment materials and particle loadings can render biphasic particles to be stimulus-responsive. (ii) Reactive coatings with one or multiple functions can be synthesized by chemical vapor deposition (CVD) polymerization [3,4] as well as CVD co-polymerization and may find use in a range of different biomedical applications [5].
