Bionanotech & Molecular Robotics Lab at TU Munich


Designing the sequences of biomolecules to construct molecular devices, machines, and autonomous systems.

Our goal is to build ultra-miniaturized molecular devices and machines that can be combined into autonomously functioning systems ("robots") capable of executing user-defined tasks. At the moment we are primarily concerned with constructing hardware. Inspired by the structural sophistication and the rich functionalities of natural molecular motors and of viruses, we investigate how to adapt the physical principles underlying the formation of these natural objects for our purposes. Important principles are self-assembly, polymer folding and the fact that structures can be encoded in polymer building block sequences. Molecular self-assembly with DNA is an attractive route toward implementing these principles to create synthetic molecular machinery. DNA origami in particular enables building nanodevices that can already be employed for making new discoveries in biomolecular physics and protein science.

 

In the long term we hope to contribute to the creation of molecular devices and autonomous systems that have practical benefits for everyday life. We pursue, among others, potential uses in medicine for advanced, more specific therapies. 

 


Opportunity for candidates with BSc: Explore how the interplay of biological building blocks can generate life and how to replicate life-like systems. Combine new technologies by learning-by-doing and creatively use biological substances to gain new insights and invent applications in the life sciences. The direct-track PhD program Matter to Life is part of the Max Planck School Matter to Life
