No / The motion of an artificial micro-scale swimmer that uses a chemical reaction catalyzed on its
own surface to achieve autonomous propulsion is fully characterized experimentally. It is shown
that at short times, it has a substantial component of directed motion, with a velocity that depends
on the concentration of fuel molecules. At longer times, the motion reverts to a random walk with
a substantially enhanced diffusion coefficient. Our results suggest strategies for designing artificial
chemotactic systems.
