Polymeric Nanostructures for Biomedical Applications
TOBB University of Economics and Technology, Ankara, Türkiye
In this lecture, I will summarize some of our efforts in designing, assembling/synthesizing, and structurally and functionally characterizing nanostructured materials using anodized aluminum oxide (AAO) as thin film template. A particularly powerful analytical tool is optical waveguide spectroscopy using the nanoporous template as the guiding structure. We demonstrate how surface initiated polymerization of N-carboxy anhydride (NCA) monomer for the fabrication of multilayer assemblies allows for the fabrication of nanotube arrays. When using - in addition to sythetic polypeptides as building blocks - also nano-objects from high-technological thermoset materials (polycyanurate) hybrid architectures can be assembled with very interesting photo-physical properties. These were employed, e.g., also for biosensing applications. Other strategies for using the AAO layers as templates include the growth of polymeric nano-rod arrays from different functional monomers which after the dissolution of the template are still able to guide light. This opens up novel concepts for integrated optics platforms with nanostructured materials.
Dr. Hatice Duran graduated from Yıldız Technical University, İstanbul, Turkey with a BE degree from the Chemical Engineering department in June 1997. She was awarded a PhD in Polymer Engineering at the University of Akron, Ohio in May 2004. In October 2004, she joined the Materials Science group lead by Prof. Wolfgang Knoll at the Max Planck Institute for Polymer Research (MPI-P), Mainz, as a Marie-Curie postdoctoral fellow. In 2008, she received a research grant within the Deutsche Forschungsgemeinschaft SPP 1369 Priority Program funded for 3 years. In November 2008, she rejoined the group of Physics at Interfaces lead by Prof. Hans.-Jürgen Butt at the MPI-P as a Project leader and she held this position until December 2010. Then, Dr. Duran joined to TOBB University of Economics and Technology (Department of Materials Science and Nanotechnology Engineering) in Ankara, Turkey. She conducts research on structural and functional properties of organic thin films, in particular supramolecular assemblies and nano-materials, synthetic biological polymers, optical biosensors and functional porous polymeric membranes.
