摘要：

(Chemical Equation Presented) Turbo nanomotors: A dramatic increase of the speed of fuel-driven nanowire motors is obtained using an Ag/Au alloy segment. These nanomotors offer speeds as high as 150 μm s-1 (75 body lengths per second), approaching those of the most efficient biomotors. The increase in the fuel decomposition rate associated with the electrochemical reactivity of Ag/Au alloys will enable the design of energy-efficient nanomotors. © 2008 Wiley-VCH Verlag GmbH & Co.
