Arrays of Nickel Nanowires

The arrays of nickel nanowires have been produced by electro-deposition of nickel into the pores of porous alumina membranes. The membrane has been resolved by chemical etching and free standing nanowires perpendicular to a substrate have been obtained. Due to their ferromagnetic properties, the nanowires have possible applications in high density magnetic recording media. The picture shows a cross section view of the nickel nanowire array.

Dendritic cell

False-colored SEM image of a migrating mouse dendritic cell (5.2 µm), showing membrane projections known as lamellipodia (green). Dendritic cells are sentinels of the immune system that are posted in peripheral tissues, ingest intruders and then migrate to the lymphoid organs. There, they expose some of their digested protein fragments (antigens) using their cell membrane as a showcase, report on the intruder and interact with- and instruct effector immune cells known as T-lymphocytes.
