DNA-programmed assembly of dendrimers and conjugated polymers — •Kurt Gothelf — Aarhus University, Aarhus, Denmark

The idea behind our research is to use DNA as a programmable tool for directing the self-assembly of molecules and materials. The unique specificity of DNA interactions, our ability to code specific DNA sequences and to chemically functionalize DNA, makes it the ideal material for controlling self-assembly of components attached to DNA sequences. We have developed some new approaches in this area such as the use of DNA for self-assembly of organic molecules[1] and position dendrimers. We have used DNA origami to assemble organic molecules, study chemical reactions with single molecule resolution [4]. We have also formed 3D DNA origami structures [5] and dynamic DNA structures [6]. In the presentation I will focus on our recent progress on self-assembly of macromolecular DNA conjugates such as dendrimers and conjugated polymers into DNA origami.
