The DNA group are based in the Clarendon Laboratory at the University of Oxford and are part of Oxford Biological Physics. Their backgrounds range from physics and chemistry to biochemistry but now they are all using DNA as a material for bionanotechnology. Recent work includes the design and characterization of DNA tetrahedra, which can serve as rigid building blocks and as molecular cages; the development of DNA motors and fuels; and the application of DNA lattices to protein structure determination.
