Influence of Physicochemical Properties of Iron Oxide Nanoparticles on Their Antibacterial Activity

“…Recently, MNPs have received attention in various fields due to their unique magnetic properties, including paramagnetism, tunable magnetism, biocompatibility, drug delivery, and antimicrobial and surface modification properties. − Like other MNPs, iron oxide nanoparticles (IONPs) are used as magnetic resonance imaging (MRI) contrast dye, biosensors, diagnosing diseases, drug delivery vehicles, pollutant removal, biomedical machinery, and antimicrobial agents. − Though divalent metals like iron ions are essential for the growth of microbes, IONPs display nonspecific antibacterial activity by generating electrostatic attraction or repulsion force and reactive oxygen species (ROS). − Moreover, other parameters could influence the antimicrobial activity of IONPs, including synthesis methods, precursors, size, and concentration . Furthermore, depending on the characteristics of the materials, the physicochemical, electrical, optical, and biological properties of IONPs can be influenced via surface modification.…”
