Sticky note origami12/25/2023 ![]() ![]() "The foundational principles from our previous paper, combined with the innovations in this one, set the stage for the future of biomimetic transmembrane machines, with the potential to harness energy from salt gradients, a vital energy source employed by biological motors. This year's breakthrough, driven by rational design, marks the next phase of our journey." Reflecting on the work, Xin Shi said, "We've unveiled the fundamental principles behind propelling a nanoscale rotor using water and salt in nanopores. ![]() This research achievement follows last year's introduction of the DNA active nanorotor, a self-configuring device capable of transforming energy from electrical or salt gradients into practical mechanical work. This design allows the direction of rotation of the turbine in our nanopores to be controlled through the handedness of the blades and allows straightforward integration of the turbine to other nanomachines.Ī new step towards active transmembrane nanomachines The "DNA origami" technique uses the specific interactions between complementary DNA base pairs to build dynamic 3D nano-objects. This unique feature, exclusive to the nanoscale realm, results from the intricate interplay between ions, water, and DNA.Ĭees Dekker, who supervised the research, sheds light on their methodology saying, "Together with our collaborators at Hendrik Dietz's lab from the Technical University of Munich, we used insights from our previous work on DNA rotary motors to now create a turbine with full control over its design and operation." Its behavior is influenced by ion concentration, allowing the same turbine to spin either clockwise or anticlockwise, depending on the concentration of Na + ions in the solution. Otherwise for future origami reference, this that were folding is called the bird base, and is used as the base for many origami animals. ![]() Step 4: Take All 4 Points and Fold to Center. Step 2: Fold From Point to Point in Half Step 3: Then Fold in Half Again From Point to Point. One of the most intriguing discoveries of this research is the unique nature of the DNA origami nano-turbine's rotation. If you already know how to fold the bird base, go ahead and do that, and you can skip this step. a pen your hands Step 1: Peel Off a Sticky Note With the Sticky Part Up. We used our turbine to drive a rigid rod up to 10 revolutions per second," says Xin Shi, lead author of the article. To operate, this structure is docked in a strong water flow, controlled by an electric field or salt concentration difference, from a nanopore, a tiny opening, in a thin membrane. Step 3: The Body Crease the paper so it stays in that triangle shape. Step 2: The Body Fold a square piece of paper into a triangle, so that one corner meets the other. "Our nanoturbine has a 25-nanometer diameter rotor made from DNA material with blades configured in a right-handed or left-handed sense to control the direction of rotation.

DNA Origami nanoturbine sets new horizon for nanomotors. ![]()
