Synthesis, electron microscopy and anti-microbial properties of Fe 3 O 4 –Ag nanotubes

Electrodeposition was used for synthesizing 200 nm diameter Fe 3 O 4 –Ag nanotubes. Compositional analysis at the single nanotube level revealed a fairly uniform distribution of component elements in the nanotube microstructure. As-synthesized Fe 3 O 4 –Ag nanotubes were superparamagnetic in nature....

Description
Summary:Electrodeposition was used for synthesizing 200 nm diameter Fe 3 O 4 –Ag nanotubes. Compositional analysis at the single nanotube level revealed a fairly uniform distribution of component elements in the nanotube microstructure. As-synthesized Fe 3 O 4 –Ag nanotubes were superparamagnetic in nature. Electron diffraction revealed the ultrafine nanocrystalline microstructure of the nanotubes. The effect of Ag on the anti-microbial response of the nanotubes was investigated by comparing the effect of sulphate reducing bacteria (SRB) on Fe 3 O 4 –Ag and Fe 3 O 4 nanotubes. Fe 3 O 4 nanotubes were also electrodeposited in the present study. It was observed that the Fe 3 O 4 –Ag nanotubes exhibited good resistance to sulphate reducing bacteria which revealed the anti-microbial nature of the Fe 3 O 4 –Ag nanotubes.
