Scientists Use Self-assembled DNA Scaffolding To Build Tiny Circuit Boards

Scientists have developed a new technique to orient and position self-assembled DNA shapes and patterns -- or "DNA origami" -- on surfaces that are compatible with today's semiconductor manufacturing equipment. These precisely positioned DNA nanostructures, each no more than one one-thousandth the width of a human hair, can serve as scaffolds or miniature circuit boards for the precise assembly of computer-chip components.
