DNA Origami nanoturbine sets new horizon for nanomotors      (via sciencedaily.com)     Original source 

Researchers introduce a pioneering breakthrough in the world of nanomotors -- 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 'DNA origami' 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.
