CoNiP/Au Multisegment Magnetic Nanowires: Synthesis and Aminothiophenol (4-ATP) Functionalization
The magnetic properties in CoNiP/Au multisegments nanowire were
investigated. All the samples were prepared by electrodeposition method
with pH of 5.5 and room temperature. The electrochemical potential of
CoNiP was determined by cycle voltammetary. The crystalline structure
and morphology of the samples were characterized by X-ray diffraction
(XRD), Scanning Electron Miroscopy (SEM) and High-resolution
transmission electron microscopy (HRTEM), respectively. The hysteresis
loops were measured at room temperature using vibrating sample
magnetometry (VSM). The SEM and TEM image showed that the CoNiP/Au
nanowires with diameters about 50 nm. The lattice spacing of the CoNiP
samples were 0.205 nm. The obtained results of VSM show that, the
coercivity is 1006 Oe. The 4-Aminothiophenol (4-ATP) functionalized
CoNiP/Au were combined by inverse emulsion method in order to apply to
biomedicine. The characteristic Surface Enhanced Raman peak positions
of 4-ATP absorbed on the Au segments were occurred without any
alterations, which significantly predicted attractive applicability of
the colloids for biomedical labeling.
