The green synthesis of environmentally friendly magnetic silver complex stabilized on MnCoFe < sub > 2 < /sub > O < sub > 4 < /sub > @sodium alginate nanoparticles (MCF@S-ALG/Ag) and evaluation of their antibacterial activity

Environ Sci Pollut Res Int. 2022 Dec 26. doi: 10.1007/s11356-022-24914-5. Online ahead of print.ABSTRACTMagnetic nanoparticles with green cover sodium alginate and Ag, MnCoFe2O4@Sodium alginate/Ag (MCF@S-ALG/Ag) MNPs were prepared by a simple and clean method from Sargassum Vulgare brown algae. The structure of these nanoparticles was characterized by the Fourier transform infrared (FT-IR), X-ray powder diffraction (XRD), field emission-scanning electron microscope (FE-SEM), energy-dispersive X-ray spectroscopy (EDX), thermogravimetric analysis (TGA), and vibrating sample magnetometer (VSM). Furthermore, the antibacterial activity of MCF@S-ALG/Ag MNPs was tested for two bacteria of gram-negative (Escherichia coli (E. coli)) bacteria and gram-positive (Staphylococcus aureus (S. aureus)) bacteria. The MCF@S-ALG/Ag MNPs showed the inhibition zone 16.32 mm for S. aureus and 12.84 mm for E. coli bacteria. The minimal inhibitory concentration (MIC) and the minimal bactericidal concentration (MBC) of MCF@S-ALG/Ag MNPs for both bacteria were found 20 µg/mL and 40 µg/mL, respectively.PMID:36571692 | DOI:10.1007/s11356-022-24914-5
