Abstract

<abstract abstract-type="graphical" xml:lang="en" id="smll201470039-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Hybrid artificial flagella (h‐ABF) consisting of a ferromagnetic alloy head and a helical polymer tail can be fabricated by sequential electrodeposition of a cobalt‐nickel alloy and polypyrrole inside a photoresist template patterned by 3D laser lithography. As M. A. Zeeshan, S. Pané, and co‐workers report on page 1284, the h‐ABFs are physically stable in an aqueous environment with a rigid connection between the metallic and the polymer segments. Controlled actuation of the microrobots by a rotating magnetic field is demonstrated in a fluidic environment with a focus on swarm control. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg52x8sn8k" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
