    • Because of the low Reynolds number prevailing in microchannels, mixing can generally not occur by turbulence and has to rely on molecular diffusion. Chaotic advection, 43 which will increase the interfacial area between two fluids, can be used to enable molecular diffusion to take place on efficient time scales

    • At the fastest point in an actuation cycle at 5 Hz, a cilia with a width of 100 m effectuates a stroke over a distance of ∼200 m in 20 ms. Therefore we can estimate the Reynolds number to be maximum 1 in our experiment. At such low Reynolds numbers, viscous effects are expected to dominate over inertial effects and temporal asymmetry in the movement will play a minor role in net flow movement Among common solvents, chloroform was found to produce the most stable colloid. When mixed with PDMS, a more stable colloid results in a magnetic PDMS with smaller particle clusters. Processing with toluene, xylene or tetrahydrofuran produced larger clusters in the PDMS than processing with chloroform. The investigated solvents were selected for being able to swell cross-linked PDMS (according to Lee et al. 45), hence having chemical affinity with PDMS monomers
