The life threatening disease of sepsis is associated with high mortality. Septic patient survivability with currently available treatments has failed to improve. The purpose of this study was to evaluate whether lipopolysaccharide (LPS) induced sepsis mortality and associated hepatic dysfunction can be prevented by cerium oxide nanoparticles (CeO2NPs) treatment in male Sprague Dawley rats. Here...

Abstract—Preparation of nanoparticles of cerium oxide and adsorption of bovine serum albumin on them were studied. Particle size distribution and influence of pH on zeta potential of prepared CeO2 were determined. Average size of prepared cerium oxide nanoparticles was 9 nm. The simultaneous measurements of the bovine serum albumin adsorption and zeta potential determination of the (adsorption)...

Abstract Cerium oxide nanoparticles have unique catalytic and oxygen storage capacity properties. In this work, the morphology size of cerium were experimentally theoretically investigated. For synthesis nanoparticles, laser ablation method was used. The analysis morphological characteristics performed using transmission electron microscopy. Using molecular dynamics, we reveal limiting dimensio...

cerium oxide (ceria) nano particle, as photodegradation prevention agent was studied in water-based polyurethane clear coat  systems. polyurethane coatings show superior weathering resistance compared with acrylic melamine systems. however, any chemical change has detrimental effects on the property profile of pu coatings. coatings containing various amounts of cerium oxide nanoparticles were p...

Interactions of nanoparticles with biological matter-both somatically and in nature-draw scientists' attention. Nanoparticulate systems are believed to be our saviors, acting as versatile drug delivery vehicles. However, they can also cause life-threatening bodily damage. One of the most important properties of nanocrystalline cerium dioxide is its antioxidant activity, which decreases the abun...

In recent years, nanotechnology has gained serious attention for diagnosis, prevention and treatment roles. In this study we synthesized nanoceria or CeO2NPs (cerium oxide nanoparticles) and compared toxicity of cerium oxide powder in nano and bulk forms in two cancerous and one normal cell lines. The cell lines were cultured in a standard humidified incubator, at 37 °C in a 5% CO2 atmosphere, ...

Gold nanoparticles supported on cerium(IV) oxide powder showing strong absorption at around 550 nm due to surface plasmon resonance oxidized aromatic alcohols to corresponding aldehydes almost quantitatively in an aqueous suspension under irradiation of green light.

nanocrystalline particles of cerium oxide (ceo2) have been prepared by the chemical precipitation method using cerium nitrate and urea with a molar ratio of 1:2. the results revealed that the formation of ceo2 fine particles is influenced by molar ratio of metal nitrates to fuel. well faceted ceo2 nanoparticles, were synthesized by thermal-assisted dissociation method at reflux temperature in a...

Hybrid supramolecular hydrogels are prepared by non-enzymatic dephosphorylation of N-fluorenylmethyloxycarbonyl tyrosine-(O)-phosphate (FMOC-Tyr-P) using catalytic cerium oxide nanoparticles. The organic-inorganic hydrogels exhibit enhanced viscoelastic properties compared with analogous materials prepared using alkaline phosphatase.
