Harnessing a paper-folding mechanism for reconfigurable DNA origami

The paper-folding mechanism has been widely adopted in building of reconfigurable macroscale systems because of its unique capabilities and advantages in programming variable shapes and stiffness into a structure. However, it has barely been exploited in the construction of molecular-level systems owing to the lack of a suitable design principle, even though various dynamic structures based on DNA self-assembly have been developed. Here we propose a method to harness the paper-folding mechanism to create reconfigurable DNA origam…

Tech for Good: Origami folding at a nanoscale

CNN's Kristie Lu Stout travels to Seoul National University in South Korea where a student, Myoungseok Kim, discovered a new way of folding already folded DNA; in essence, origami of DNA origami. DNA Origami as a field has been around since 2006. It applies short strands (known as staples) programmed with specific bases along a long single strand of DNA, folding them according to the base bonds to make all types of shapes. Previously, DNA origami could only fold once, but by modeling DNA structures after paper creases, Kim and his pro…

Supercomputer-Assisted Simulation Research on DNA Origami Structures

To understand the interactions and binding phenomena within DNA material, extensive computational simulations utilizing supercomputers are necessary. Utilizing the 5th generation supercomputer, Nurion, we present research that employs massive calculations to model the formation, binding, and folding of DNA megastructures, as well as the technology of DNA origami.
