Abstract
Superparamagnetic nanocomposites have imposed a significant impact on progress in optical, magnetic, and drug delivery characteristics. Employing nitrate-citrate sol-gel method the Ce4-xCs2(1+x)Fe5-xZnxO14+δ (0≤x≤0.45) (CCFZ Nanocomposites) have been prepared, which exhibit spherical and honeycomb-shaped morphologies. CCFZ Nanocomposites was characterized by energy-dispersive spectroscopy (EDS), field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscopy (HR-TEM), X-ray photoelectron spectroscopy (XPS), FT-IR spectroscopy, Raman spectroscopy, photoluminescence (PL), and UV spectroscopy. The prepared CCFZ NCs were polycrystalline in nature and portrayed superparamagnetic behavior confirmed by XRD and VSM studies, respectively. The phase formation of CCFZ NCs was ensured from the X-Ray diffractograms. FE-SEM images revealed spherical and honeycomb-like structures, which confirmed the presence of cavities in the samples. The mean size of the synthesized CCFZ nanocomposite particles was noticed to lie below 10 nm. The BET surface areas of CCFZ (TB1-TB4) NCs were determined, which was observed to be 25.92, 13.59, 4.20, and 25.55 m2/g, respectively. The Ms values for samples TB1, TB2, TB3, and TB4 samples were 6.1624, 7.08472, 23.9184, and 6.95402 emu/g. For CCFZ nanocomposites, drug encapsulation was found to be 45%, and the drug release was examined in two steps and sustained up to period 10 h at pH 7.4.
