Research Focus

The overarching effort in our lab is to develop new DNA-based methods and molecular tools for cell biology research.

Molecular tools for cell biology

By using DNA-origami, we are able to construct precise patterns of different molecules on a nanometer scale. Using these we can probe the effect the distance has on a number of cellular mechanisms. In this effort we use cell culture, superresolution microscopy, electron microscopy and next generation sequencing.

Development of DNA self-assembly technology

A second part of the lab is focused on research on the basics of DNA self-assembly and DNA nanotechnology to improve their suitability for the above applications. Among other things we are developing a new design paradigm for DNA nanotechnology using a new type of triangulated meshes.

Synthetic biology for DNA nanotechnology

Lastly, a part of the lab develops synthetic biology/microbiology -methods to produce the building blocks we need for our nanostructures in bacteria. The ultimate goal is to engineer bacteria to mass produce through large scale cultures, all components necessary for the DNA-origami/protein nanostructures we need for our biological applications.

 

Using DNA as a construction material

By using the method of DNA origami , we are able to design and fabricate nanoscale devices as if we were using macro-scale techniques. This video introduces briefly some of our applications.
