In this manuscript, a simple new method for the green synthesis of platinum nanoparticles (Pt NPs) utilizing F. carica Fig extract as reducing agent for antimicrobial activities was reported. Simultaneously, the microstructural and morphological features of the synthesized Pt NPs were thoroughly investigated. In particular, the attained Pt NPs exhibited spherical shape with diameter range of 5-30 nm and root mean square of 9.48 nm using Transmission Electron Microscopy (TEM) and Atomic Force Microscopy (AFM), respectively. Additionally, the final product (Pt NPs) was screened as antifungal and antibacterial agent against Candida and Aspergillus species as well as Gram-positive Staphyllococcus aureus and Gram-negative Acinetobacter species, respectively. Accordingly, the synthesized NPs demonstrated inhibition zones of 36 and 28 mm against fungal and bacterial species, respectively. The presented Pt NPs play an active role in both antifungal and antibacterial activities which indicates the presence of a well-regulated nano-materials system for biomedical application.

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.
