ABSTRACT:

Iron oxide nanozymes are tiny substances that resemble enzymes and are being researched for their capacity to fight bacterial infections because of their efficacy and durability. This study examined the antibacterial properties of iron oxide (FeO₄) nanozymes against the common gut bacterium Escherichia coli (E. coli). The ability of the nanozymes to stop bacterial growth was examined after they were created using chemical co-precipitation. The concentration was 1 mg/mL, and antibacterial effectiveness was determined using agar plate tests. At this concentration, Fe₃O₄ nanozymes were found to successfully kill E. coli cells. Fe₃O₄ nanozymes can limit bacterial growth at low doses, according to recent research. Additional research, such as minimal Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) assays, is needed to establish the minimal effective dose required to inhibit or kill E. coli. This study emphasizes the potential of iron oxide nanozymes as efficient antibacterial agents, paving the path for further research into their broader applications in bacterial illness management.
