Abstract

Nanosized ferrites MgxZn1-xFe2O4 (0 < x <1) was effectively synthesized using a wet ferritization method. The obtained spinel nanoparticles were then treated with flavonoids (Flv) extracted from agricultural waste of Punica granatum L. and Allium cepa L. Various characterization techniques such as FTIR, XRD, DTA-TGA, VSM, FE-SEM, TEM, EDX, and BET were utilized to analyze the surface morphology, magnetic properties, and elemental composition. The X-ray diffractograms revealed that the synthesized MgxZn1-xFe2O4 (MZFO) nanoparticles displayed a uniform cubic spinel structure, indicating the presence of a single phase. Morphological analysis revealed two distinct categories of MZFO nanoparticles: flower-shaped and plate-shaped particles. The attendance of Mg, Zn, O, Fe, and C elements in both MZFO and Flv/MZFO samples was confirmed by EDX analysis. TEM analysis further confirmed that each particle of the modified MZFO sample was a single crystal with an average particle size of 22 nm. Additionally, the modified MZFO nanoparticles exhibited a weight loss of 39.17% due to surface modification. Notably, the modified MZFO nanoparticles displayed remarkable superparamagnetic behavior with a saturation magnetization of up to 41.875 emu.g-1. BET analysis demonstrated that the Flv/MZFO nanoparticles possessed a mesoporous structure with a total pore volume of 0.1349 cm3/g, an average pore size of 17.044 nm, and a specific surface area of 31.655 m2/g. The conjugated Flv/MZFO nanoferrites exhibited significant antibacterial efficacy, with inhibition zones of 7 mm and 8 mm against Gram-positive and Gram-negative bacteria, respectively.
