Electrodeposited magnetic nanowires are a novel type of anisotropic nanoparticle that have a wide variety of potential applications, from magnetic sensing to biotechnology. We have recently undertaken studies to explore chemical functionalization, magnetic manipulation, and self-assembly of suspensions of these nanowires. The image above shows Ni nanowires suspended in a hexadecane/octadecane mixture, and aligned in a small (8 Gauss) magnetic field. The nanowires have been functionalized with luminescent porphyrin molecules, and display strong fluorescence, as shown in the figure above.
