DNA Origami nanoturbine sets new horizon for nanomotors
A collaborative team of researchers led by prof. Cees Dekker at TU Delft, in partnership with international colleagues, introduces a pioneering breakthrough in the world of nanomotors â the DNA origami nanoturbine. This nanoscale device could represent a paradigm shift, harnessing power from ion gradients or electrical potential across a solid-state nanopore to drive the turbine into mechanical rotations. The core of this pioneering discovery is the design, construction, and driven motion of a âDNA origamiâ turbine, which features three chiral blades, all within a minuscule 25-nanometer frame, operating in a solid-state nanopore. By ingeniously designing two chiral turbines, researchers now have the capability to dictate the direction of rotation, clockwise or anticlockwise. Their research findings have been published in Nature Nanotechnology on October 26.
