Description
Summary:In this paper, we describe utilizing sustainable chemistry for the synthesis of Fe 3 O 4 , Cu nanoparticles (NPs) and Fe 3 O 4 /Cu nanocomposite (NC) employing Rosmarinus officinalis L. (rosemary) leaf extracts. The extracts of rosemary leaf are capable of producing Cu, Fe 3 O 4 nanoparticles and Fe 3 O 4 /Cu NC. The extracts of rosemary leaf were used as reducing agents for the biosynthesis of Cu, Fe 3 O 4 NPs and Fe 3 O 4 /Cu NC. The synthesized Fe 3 O 4 /Cu NCs are environmental-friendly, non-toxic materials and free of chemical contaminants. The synthesized Fe 3 O 4 , Cu NPs and Fe 3 O 4 /Cu NCs were characterized using UV–Vis spectrophotometer, X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM) and SEM/EDX techniques. The size of Fe 3 O 4 /Cu NC was found to be in the range of 36–67 nm. The antibacterial activities of rosemary extracts and biosynthesized Fe 3 O 4 /Cu NC materials were investigated using conventional methods such as well diffusion, minimal inhibition concentration (MIC) and minimum bactericidal concentration (MBC). When antibacterial activate Cu NPs were combined with Fe 3 O 4 NPs and Fe 3 O 4 /Cu NCs, we observed antimicrobial activities for the materials that we investigated. We also observed that Fe 3 O 4 /Cu NCs which were produced by green synthesis have shown antibacterial activities. Graphical abstract
