Rational Design and Synthesis of Catalytically Driven Nanorotors

Abstract

We report the design and synthesis of nanorotors based upon on-wire lithography. Because of their asymmetric structure, the nanorotors exhibit rotation in a H₂O₂ bath instead of linear motion. By observing the leading edge of rotation and comparing this result to the nanorotor design, we have concluded that the driving force for motion is dynamic catalytic decomposition of H₂O₂ which propels, rather than pulls, the nanorotor.
