Lithography: Hybrid Helical Magnetic Microrobots Obtained by 3D Template‐Assisted Electrodeposition (Small 7/2014). Issue 7 (April 2014) - Zeeshan, Muhammad A.
Abstract 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.
