Fastening azide-functionalised gold nanoparticles onto modified DNA holds great promise for nanoscale electrical circuits, say German researchers.
The trend for miniaturisation in electronics, and size and cost limitations of conventional lithographic techniques, has led researchers to develop alternative routes to nanoelectronic components. DNA is a useful template for nanoscale electronic devices, explained Simon from the Institute for Inorganic Chemistry, Aachen, Germany, due to its well-defined structure and many electrostatic and chemical binding sites which can be modified.
