NanoEngineers Use DNA to Place Nano Scale Materials

NanoEngineering professor Jennifer Cha recently published new work on using biomolecules, such as DNA and proteins, to engineer the orientation and placement of nano scale materials into the desired device architectures that are reproducible in high yields and at low costs.

The paper titled “Large Area Spatially Ordered Arrays of Gold Nanoparticles Directed by Lithographically Confined DNA Origami,” appeared in Nature Nanotechology.

“Self-assembled structures are often too small and affordable lithographic patterns are too large,” said Albert Hung, lead author of the Nature Nanotechnology paper and a post doc working in Cha’s Biomolecular Materials and Nanoscale Assembly Lab. “But rationally designed synthetic DNA nanostructures allow us to access length scales between 5 and 100 nanometers and bridge the two systems."
