A) Confluent UMR-106 tumor cells: alignment experiment. Cell with nanowires exposed to 0.1 T for 18 hrs and then cultured to confluent layer for 5 days. The nanowires in this case are about 10 μm long. B) Colony of UMR-106 cells containing nickel nanowires (bright field contrast micrograph, mag. ×40). C) Colony of UMR-106 cells containing nickel nanowires (phase contrast micrograph, mag. ×40). Diagram of cell structures and internalized wires have been highlighted under the same z-focus level.
