Figure 2

(a) Hysteresis curves for Fe nanowires (blue), Ni nanowires (red), and paramagnetic iron oxide beads (yellow). (b) SEM image of ferromagnetic Ni nanowires. (c) SEM image of paramagnetic beads; note the debris around the beads is likely a coating (d). Fluorescent microscopy images of Ni nanowires coated with fluorescently-tagged monomers, note these nanowires were not used for cell enrichment experiments.
