A Novel Green Biosynthesis Approach and Structural Characterization of Ag–Fe Bimetallic Nanoparticles using the Red Alga Galaxaura rugosa

Article scientifique 2023 Anglais

Résumé

Abstract A Novel green and eco-friendly approach has been used to biosynthesize Ag-Fe bimetallic nanoparticles (Ag-FeBNPs), mediated by an aqueous extract of the red alga species; Galaxaura rugosa. The surface plasmon resonance band is positioned at 264 nm for Ag-FeBNPs. X-ray diffraction analysis (XRD) illustrated the crystalline nature of biogenic nanoparticles. Transmission electron microscopy (TEM) and selected area electron diffraction (SAED) showed that the particles have a crystalline spherical shape with a size range from 14.3 to 22.1 nm. Scanning electron microscopy (SEM) and Energy dispersive analysis (EDAX) give the surface morphology and elemental composition of Ag-FeBNPs which is spherical in high intensity. Fourier transmittance infrared spectroscopy (FTIR) showed that the biomolecules are responsible for forming and stabilizing Ag-FeBNPs. Zeta potential values show − 15.7 mV. The findings of this study documented the great potentiality of Ag-FeBNPs that would significantly impact the field of nanobiotechnology and nanoscience in the future.
