Abstract

In the present article, we have synthesized CoFe/Au/CoFe multisegment nanowires by electrochemical deposition technique and selectively functionalized the surface of Au segmentwith cysteamine for biological and chemical applications. Themorphological structure was examined by scanning electronmicroscope and found that the nanowires are around 4 μm in length. The magnetic property of the nanowireswas measured by vibrating sample magnetometer. We have compared the magnetic properties of CoFe/Au/CoFe multisegment nanowires with CoFe nanowires and found that there is a decrease in magnetic moment for multisegment nanowires. The Au segment of the fabricated multisegment nanowires is selectively functionalized with cysteamine. The average composition and the surface functionalization of nanowires were confirmed through electron dispersive spectroscopy and X-ray photoelectron spectroscopy.
