Researchers at the University of Sydney Nano Institute have made a significant advance in the field of molecular robotics by developing custom-designed and programmable nanostructures using DNA origami.
This innovative approach has potential across a range of applications, from targeted drug delivery systems to responsive materials and energy-efficient optical signal processing. The method uses “DNA origami,” so-called as it uses the natural folding power of DNA, the building blocks of human life, to create new and useful biological structures.
As a proof-of-concept, the researchers made more than 50 nanoscale objects, including a “nano-dinosaur,” a “dancing robot” and a mini-Australia that is 150 nanometers wide, a thousand times narrower than a human hair.
