Well established synthesis procedures and the "programmability" of DNA binding via base pairing makes DNA ideal for the design of nanostructures.
We here investigate the mechanical characteristics of self assembled tetrahedra from DNA oligomers with dimensions smaller than 10nm. For this purpose, the tetrahedra are modified to bind to gold surfaces and are studied by atomic force microscopy in combination with fluorescence microscopy.
