Controlling length and areal density of artificial cilia through the dipolar assembly of ferromagnetic nanoparticlesElectronic supplementary information (ESI) available: real time video of Fig. 8B being actuated by a 1 Hz sinusoidal field (Video S1), and a real time video of the initial stages of cilia assembly for 36 nm PS-CoNPs (Video S2).

Artificial cilia have been explored for use in microrobotics, MEMS, and lab-on-a-chip devices for applications ranging from micromixers, microfluidic pumps, locomotion, acoustic detection, and heat transfer. We have previously demonstrated the ability to assemble dense brushes of magnetically actuat...
