“…4) revealed that the bacterial growth was decreased by increasing the concentrations of the nanoparticles. Similar results were reported by Sanpo et al (2013a) who reported an antibacterial activity of (CoFe 2 O 4 ) NPs against E. coli and S. aureus. In the same trend the rate of inhibition of E.coli was higher than that of S. aureus.…”

“…Metal-oxide nanoparticles draw attention due to their unique magnetic properties and other characteristics such as excellent chemical stability and mechanical hardness (Meng et al, 2009;Phua et al, 2009;Sanpo et al, 2013). Cobalt ferrite (CoFe 2 O 4 ) nanoparticles offer potential applications in several fields such as food, medicine, cancer treatment (Jamon et al, 2009) and other applications (Amiri and Shokrollahi, 2013;Sanpo et al, 2013a). These applications depend on the properties of ferrite which in turn depend on the conditions of preparation, the size and shape of the nanoparticles.…”

Recently, the application of nanotechnology in food sector and the agriculture attract the attention compared to its biomedical application. The aims of the current study was to synthesize and characterize cobalt ferrites nanoparticles [(CoFe2O4) NPs] by combustion method employing glycine as fuels and to evaluate their antimicrobial against pathogenic bacteria and fungi and anti cancer properties against MCF-7 breast cancer cells line. The results indicated that the particles size of the synthesized (CoFe2O4) NPs was 40 nm. These (CoFe2O4) NPs showed potential antibacterial properties against Gram-negative bacteria (Escherichia coli, Salmonella typhi) and Gram-positive bacteria (Staphylococcus aureus, Bacillus cereus) as well as the pathogenic fungi (Aspergillus flavus and Aspergillus ochraceus) in a dose dependent manner with maximum concentration of 1.8 mg/ml. (CoFe2O4) NPs also showed weak antiradical but have cytotoxic effects against MCF-7 breast cancer cells line and succeeded to decrease the cell viability at a concentration of 2 mg/ml. It could be concluded that (CoFe2O4) NPs is a promise candidate as antimicrobial and anticancer agent for food sector and medical application.

“…[1][2][3][4][5] The spinel ferrites exhibit two types of structures: a normal spinel structure and a partially/completely inverse structure. [4,6,7] The cobalt ferrite (CoFe2O4) is an inverse spinel in which the degree of inversion depends on the synthesis parameters and the thermal history.…”

Chromium substituted cobalt ferrites (CoFe2-xCrxO4, 0  x  2) were synthesized through solution combustion method using glycine as fuel, named glycine-nitrates process (GNP). As evidenced by X-ray diffraction data (XRD), single cubic spinel phase was formed for all CoFe2−xCrxO4 (0  x  2) series. The cubic lattice parameter (a) decreases with increasing chromium content. Room temperature 57 Fe Mössbauer spectra revealed the Fe 3+ and Cr 3+ site occupancy, the local hyperfine magnetic fields and the substitution of Fe 3+ by Cr 3+ in the lattice. Scanning electron microscopy (SEM) showed a refinement of particle size with the increase of Cr 3+ content. Magnetic measurements from 5 K to 120 K have shown a dropping in the saturation magnetization as the chromium content increases. This behaviour has been explained in terms of substitution of Fe 3+ by Cr 3+ in the cubic lattice of cobalt ferrite.

“…18,23,24 CZF were shown to have good electromagnetic performance and excellent chemical stability so they are promising candidates for biomedical application. 25 However, their biological effect has not been studied in much detail. They were tested in vitro with silica coating in rMSCs 22 and in human prostate cancer cell lines (DU145 and PC3) with biocompatible dimercaptosuccinic acid (DMSA) coating.…”
