Phyto-assisted Preparation of Fe₂O₃ Nanoflowers and Their Antimicrobial Studies

Abstract

Synthetic protocols for the preparation of nanomaterials chemically are expensive, too much time taking and unfriendly to the environment, therefore, phyto-assisted approach has the potential to be a promising alternative strategy for the synthesis of nanomaterials. Herein, Fe2O3 with nanoflower-like architecture (Fe2O3 NFs) was prepared using Moringa oleifera leaf extract, and characterized by employing several analytical techniques. The antimicrobial activity of the prepared Fe2O3 NFs was evaluated against the bacteria viz. Salmonella typhi, Staphylococcus aureus, Bacillus subtilis, Escherichia coli by using the serial dilution method. The results suggested that Fe2O3 NFs possess comparable antimicrobial activity comparable with streptomycin against the used pathogens.

Bio-capped multifunctional CuO nanoparticles via Knautia arvensis for dye removal, antibacterial and antifungal efficiency, and molecular docking

“…Metallic nanoparticles consist of various metals and their oxidized forms, and important physical properties such as shape and size can be changed by changing the ambient conditions during their synthesis. The obtained nanoparticles are highly reactive to environmental substances due to their strong surface energies [1]. Perhaps because of these properties, its antibacterial, antifungal, anti-inflammatory, antioxidant and antitumor activities have been reported in many studies [2].…”
