FIG. 1.

(a) Schematic of the device indicating the relevant geometric dimensions. (b) Magnetic hysteresis loop on the patterned sample measured along the x-direction. (c) The chip (III) with the chip holder (IV), the adhesive tape (II) and the glass lid (I) prior to assembly of the microfluidic system. (d) Schematic of the assembly of parts (I)-(IV) of the fluidic system (enhanced online). [URL: http://dx.doi.org/10.1063/1.4704520.1]10.1063/1.4704520.1

FIG. 2.

The top row shows the normalized energy calculated using COMSOL at a distance of 1 μm from the substrate over a single stripe surface for (μ0 H app,x [mT], μ0 H app,z [mT]) = (0, 2.5), (5, 2.5), (5, −2.5), (0, −2.5) and (0, 2.5) in parts (a)–(e), respectively. The bottom row shows the corresponding experimental images (enhanced online). [URL: http://dx.doi.org/10.1063/1.4704520.2]10.1063/1.4704520.2

FIG. 3.

Parts (a) and (b) show two frames from the video M2 corresponding to steps (a) and (d) in Fig. 2 for M-280 and MyOne beads with t f = 180 ms. Only the M-280 beads are able to cross the stripe (light color). (c) Sequence of frames from the video M3 where a field sequence with t f = 140 ms is applied. The M-280 beads are translated in the negative x-direction, whereas the MyOne beads (small dots mainly visible on the left side) are left behind (enhanced online).
