Enhanced antibacterial performance of Fe$_3$O$_4$�?�Ag and MnFe$_2$O$_4$�?�Ag nanocomposites

[摘要] In this work, we have described the antibacterial activities of Fe$_3$O$_4$ nanoparticles with different organic parts, including Humic acid (HA), Nicotinic acid (Nico) and Histidine (His), and the antibacterial activity ofMnFe$_2$O$_4$ nanoparticles coated with PANI and SiO$_2$ against different bacteria and some standard antibacterial drugs. The present study revealed that the newly fabricated various Fe$_3$O$_4$ and MnFe$_2$O$_4$ nanocomposites, when combined with some different organic parts, are superior antibacterial agents. Also, the synthesized nanocomposites can be easily separated from aqueous solution by magnetic filtration without any contamination of the medium.
