Cancer is one of the most common diseases nowadays and derives from uncontrollable growth a single cell. Magnetic nanoparticles (NpMag) offer various possibilities for use in biomedical area, including drug delivery mediated by magnetic fields. In current study, we evaluated vitro effects iron-oxide conjugated with antitumor doxorubicin (Dox) on human breast cancer cells. Our results revealed that Dox (NpMag+Dox) induce cellular redox imbalance MCF-7 We also demonstrate functionalized...
The incidence of female breast cancer has increased; it is the most commonly diagnosed cancer, at 11.7% total, and fourth highest cancer-related mortality. Magnetic nanoparticles have been used as carriers to improve selectivity decrease side effects on healthy tissues in treatment. Iron oxide (mainly magnetite, Fe3O4), which presents a low toxicity profile superparamagnetic behavior, attractive characteristics for this type application biological systems. In article, synthesis...
Cobalt ferrite magnetic nanoparticles (CFO) and CoFe2O4:BaTiO3 (CFO:BTO) nanocomposites were synthesized successfully by a polymeric method combination of citrate-gel methods, respectively. Nanoparticles with uniform shape, good size distribution core-shell microstructure observed transmission electron microscopy images. X-ray diffraction ATR-FTIR results attested cubic spinel structure for CFO composites core, as well BTO tetragonal perovskite shell. All samples presented ferrimagnetic-like...
Fe3O4 nanoparticles coated with chito-oligosaccharides (COS) were prepared in situ by a simple co-precipitation method through mixing of iron ions (Fe3+ and Fe2+) COS aqueous solutions followed precipitation ammonia. The impact different degree polymerization (DP 10, 24 45) N-acetylation (DA) ∼ 24% 50% (exhibiting high solubility) on the synthesis physical properties magnetic was evaluated. Several advantages found when presence studied COS, such as: preparation functionalized narrower size...
In this paper, the photocatalytic activity of bismuth ferrite particles synthesized by high-energy ball milling is evaluated considering degradation methylene blue solutions. Once chemical routes are extensively used to produce these kind reactors, mechanochemical route has advantage large-scale and low-cost production. The structural, microstructural optical properties powders investigated efficiency experimentally proved. results show a 95% dye, which became complete after addition H2O2...
In this paper, three well-known prototypic ferroic materials, BaTiO3, PbZr0.4Ti0.6O3 and Fe3O4, were experimentally theoretically investigated to explore the origin of their respective state. Their structural properties determined by X-ray powder diffraction Rietveld refinement. The electron density distribution around cationic anionic sites obtained using Maximum Entropy Method on analyzing results. Electron distributions electronic band structures Density Functional Theory simulations...
The use of a variety microorganisms for the degradation chemicals is green solution to problem environmental pollution. In this work, fungi–magnetic nanoparticles were studied as systems with potential be applied in remediation and pest control agriculture. High food demand puts significant pressure on increasing herbicides, insecticides, fungicides, pesticides, fertilizers. global water pollution also demands new solutions. As sustainable alternative commercial chemical products,...
BiFeO3 nanoparticles (<200 nm) were synthesized using the Pechini method and submitted to structural, microstructural, magnetic electrical investigations. Two different structural symmetries proposed describe structure observed properties, rhombohedral (R3c space group) orthorhombic (Pbmn). Electric conductivity results obtained as a function of temperature, show two completely reversible changes in baseline (310 °C 385 °C), indicating corresponding transitions associated with symmetries....
