Antimicrobial Activities of Green Biosynthesized Iron Oxide Nanoparticles Using F. Carica Fruit Extract

Abstract

In the current study, iron oxide nanoparticles (IO NPs) were synthesized via modified green synthesis technique using F. carica fig extract as reducing agent. Furthermore, the microstructural properties of the synthesized IO NPs have been thoroughly elucidated. In details, the acquired NPs diameter was found to be in the range of 11-29 nm and of root mean square (RMS) of 0.64 nm using TEM and AFM techniques, respectively. Consequently, the antifungal and antibacterial activities of the synthesized IO NPs were screened against Candida and Aspergillus species as well as Gram-positive Staphylococcus aureus and Gram-negative Acinetobacter species, respectively. The presented IO NPs play an active role in the antimicrobial activities evidencing the well-organized materials system for biomedical applications.
