Nanowires of Ru are a promising candidate for studying the intrinsic behavior of individual one-dimensional superconducting wires. We have prepared Ru nanowires by electrochemical deposition in porous polycarbonate membranes and characterized them structurally by high-resolution transmission electron microscopy and electron diffraction. Ru wires with diameters of 50 and 100 nm were found to be polycrystalline, consisting of ultrasmall Ru grains with a typical size of 2 nm. Metallic contacts to arrays of Ru nanowire as well as individual wires were made. Electrical transport measurements showed that these wires were metallic, but not superconducting down to 0.3 K.
