Precision Polymer Engineering through Biomolecular Templates — •David Ng, Sean Harvey, Yu Tokura, and Tanja Weil — Max Planck Institute for Polymer Research, Mainz, Germany

Nature provides a host of macromolecules that are both specific in their functions as well as sequence. The absolute atomic positioning in three dimensional space provides a precision scaffold unrivalled in the synthetic world even in the years to come. It is therefore intuitive that by combining the vast spectrum of knowledge on protein and DNA architectures with polymer chemistry, a new platform that allows the customization of nanoscale features can be evolved.

In the first part, we will discuss the conceptual design of using the protein structure as a backbone to position polymers. Depending on the chemistry and the strategy, materials ranging from anisotropic hybrid nanostructures to stimulus responsive hydrogels can be constructed. In the second part, DNA origami technology is used to provide true programmable features. Persistent shapes that do not exist in nature can be first templated by the origami by which polymers can be designated and grown in limitless possibilities in a three dimensional space. Collectively, we show that the incorporation of bioarchitectures into nanotechnology is multifold, with implications that impact the design as well as further application of such systems.
