Ultrathin nanowires are very attractive because they have unique catalytic and optical properties. Ultrathin nanowires are generally prepared in organic solvents
hence, the preparation of water-dispersible ultrathin nanowires is necessary in order to expand their areas of application. Furthermore, bimetallic nanocrystals are emerging as a new class of material. Herein, we report the preparation of water-dispersible Au–Ag bimetallic ultrathin nanowires by the orient-attachment method using a long-chain amine (C18AA) as the capping agent. These nanowires have an average diameter of 2 nm and lengths of a few micrometers
these lengths are controlled within the nanometer-to-micrometer range by adjusting the [C18AA]/[Au+Ag] molar ratio. In addition, these ultrathin nanowires exhibit a surface-plasmon band in the infrared region.
