Abstract

<abstract abstract-type="toc"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <graphic position="anchor" id="ga" xlink:href="ark:/27927/pgj2qrqpgtx" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" />Self-propelled Janus colloids show enhanced active motion when trapped at the water surface. Trajectories are more directional and velocities are higher than those in the bulk. The confinement effect given by the air–water interface strongly reduces the rotational motion of the colloid while not hindering self-propulsion.</p> </abstract>
