The golden age of DNA: We describe a strategy for engineering bifunctional proteins that simultaneously associate with metals and DNA to create self-assembled nanostructures. A DNA binding protein engineered with a gold binding peptide arranges colloidal gold particles along a DNA guide by virtue of its introduced peptide motif. These self-assembled complexes represent a step toward constructing nanoarchitectures with potential in nanoelectronic and photonic devices.
