Inspired by the rich functionalities of natural macromolecular assemblies such as enzymes, molecular motors, and viruses, we investigate how to build increasingly complex molecular structures. Our goal is to build molecular devices and machines that can execute user-defined tasks. Molecular self-assembly with DNA is an attractive route toward achieving this goal. 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 machines and systems that have practical benefits for everyday life. This includes potential uses in medicine – for diagnosis and therapy – and synthetic enzymes for biologically inspired chemistry.
