DNA origami is an emerging field of nanotechnology that exploits the unique base-pairing capabilities of the DNA bases to produce complex and mechanically stiff self-assembled nanoscale geometries. Recently, DNA origami has found uses in applications such as single molecule sensing, drug delivery and templating molecular components.
This review, by researchers from Ohio State University, sets out to explore the mechanical nature of DNA nanostructures in order to understand how these structures will respond to physical interactions. The review covers three major areas of progress, including measuring and designing mechanical properties of DNA nanostructures, designing complex nanostructures based on imposed mechanical stresses and, finally, designing and controlling structurally dynamic nanostructures.
For researchers interested in the future possibilities of DNA origami, this review should provide an insightful first stop for discussing the mechanical design of DNA nanostructures.
