Moran publishes paper on catalytic nanomotors in the Journal of Fluid Mechanics

Abstract: Mitchell originally proposed that an asymmetric ion flux across an organism’s membrane could generate electric fields that drive locomotion. Although this locomotion mechanism was later rejected for some species of bacteria, engineered Janus particles have been realized that can swim due to ion fluxes generated by asymmetric electrochemical reactions. Here we present governing equations,… Read more »

Moran and Wheat publish in PRE

Jeff Moran and Philip Wheat publish paper on electrokinetic locomotion in Physical Review E. Bimetallic rod-shaped nanomotors swim autonomously in hydrogen peroxide solutions. Here we present a scaling analysis, computational simulations, and experimental data that show that the nanomotor locomotion is driven by fluid slip around the nanomotor surface due to electrical body forces. The… Read more »
