    New DNA Origami Motor Breaks Speed Record for Nano Machines

    March 6, 2020, Categories  Health/Medical, Chemistry/Nanotechnology, Biology/Biotechnology

    Sixteen strands of DNA, stacked four-by-four, form the beam-shaped “chassis” of the DNA motor (in gray). Bits of DNA (in green) protrude from the chassis like little feet. The motor is fueled by RNA laid on a track. The RNA binds with the DNA feet on the bottom face of the chassis. An enzyme targeting bound RNA then destroys these RNA molecules (grey and red). The process repeats, as more RNA pulls the DNA feet, tipping the chassis forward, causing it to roll. (Stephanie Jones, bio-illustrations.com)

    Scientists pave way for ‘nano bots’ to one day diagnose and treat disease. Through a technique known as DNA origami, scientists have created the fastest, most persistent DNA nano motor yet...
