Summary

S.Howorka1-0613

The Howorka group works within the areas of nanobiotechnology and synthetic biology on the assembly of bio-polymers into nanoarchitectures with new functional properties. The rationally designed nanostructures include DNA-based nanopores, protein nanolattices, and nanopatterned polymer films. Techniques for chemically modifying the bio-polymers play a key role in order to tailor the nanostructures’ properties for applications in biomedicine, biosensing, and biological research. Furthermore, single-molecule detection helps to characterise the nanostructures or to demonstrate their functional properties.
