Electrochemical Synthesis and Characterization of NiFe/Au Multisegmented Nanowires
This paper represents the synthesis and characterization of NiFe single segment and NiFe/Au multisegmented nanowires. We fabricated these nanowires by electrodeposition technique using track etched polycarbonate membrane as a template with a nominal pore diameter of 50 nm. In recent years, much attention has been drawn to magnetic and nonmagnetic multisegmented nanowires because the magnetic properties of the nanowires can be useful for the manipulation and detection of biomolecules in a suspension by the application of relatively small magnetic fields where as the nonmagnetic segment has biocompatibility with high surface functionality. So in this work we studied the growth of NiFe/Au multisegmented nanowires. The length of the nanowires is found to be very uniform. The magnetic properties are measured by VSM. The measured coercivity and saturation magnetization of NiFe/Au multisegmented nanowires are lower than the NiFe nanowires. The structural morphology was observed by SEM. The EDS result shows the purity of both NiFe nanowires and NiFe/Au multisegmented nanowires.
