BACKGROUND Magnesium oxide nanoparticles (MgO nanoparticles, with average size of 20 nm) have considerable potential as antimicrobial agents in food safety applications due to their structure, surface properties, and stability. The aim of this work was to investigate the antibacterial effects and mechanism of action of MgO nanoparticles against several important foodborne pathogens. RESULTS R...

introduction: some studies show magnesium has anticonvulsive effect in some animal models. despite of the availability of well-studied anticonvulsant drugs, this evaluation was not carried on new kind of magnesium supplement, magnesium oxide nanoparticles (nmgo). according to the interaction between magnesium and convulsion, this study was designed to evaluate the effect of nmgo on strychnine-i...

High quality double-walled carbon nanotubes (DWNTs) were synthesized by decomposition of methane over cobalt (Co) nanoparticles supported on porous MgO nanoparticles. The growth was significantly influenced by catalyst concentration and MgO type. Catalysts with 2.5–5 wt% Co loaded MgO (pore size: 4 nm) efficiently grow DWNTs with diameters of 2–4 nm, high graphitization, clean surfaces, and cle...

A wet chemical preparation of MgO with the (111) facet as the primary surface has recently been reported and with alternating layers of oxygen anions and magnesium cations, this material shows unique chemical and physical properties. The potential to utilize the MgO(111) surface for the immobilization of metal particles is intriguing because the surface itself offers a very different environmen...

background and aims: although metal and metal oxide nanoparticles are used in different medical applications, they may have considerable toxicity on various cells, such as myocytes. therefore, this study aimed to evaluate the toxicity of the naked and serum-treated silver nanoparticles (ag nps) and magnesium oxide nanoparticles (mgo nps) on the cardiomyocytes. materials and methods: cardiomyocy...

OBJECTIVES According to importance and increasing application of nanoparticles and their toxicity, the identification effects of nanoparticles on physiological systems are essential. Some studies show magnesium has analgesic effect in some pain models but this evaluation was not carried on nano-magnesium oxide (MgO). Thus, present study was designed to evaluation effect of Mgo nanoparticles alo...

Magnesium in the body regulates nucleic acid chemistry, mediates cell-cell and cellextracellular matrix (ECM) interactions via integrin activation, and directly influences mineral formation and resorption in bone. Importantly, magnesium oxide (MgO) nanoparticles also exhibit powerful antibacterial properties. Here, MgO nanoparticles were dispersed within poly-L-lactic acid (PLLA) composites and...

Nanocomposite membranes composed of polymer and inorganic nanoparticles are a novel method to enhance gas separation performance. In this study, membranes were fabricated from polysulfone (PSf) containing magnesium oxide (MgO) nanoparticles and gas permeation properties of the resulting membranes were investigated. Membranes were prepared by solution blending and phase inversion methods. Morpho...

The antifungal activity of zinc oxide (ZnO) and magnesium oxide (MgO) nanoparticles prepared by bio-safe method was evaluated for Alternaria alternate, Fusarium oxysporum, Rhizopus stolonifer and Mucor plumbeus. It was observed from the study that all the nanoparticles at different concentrations brought about significant inhibition in the germination of spores of Alternaria alternata, Fusarium...

Green synthesis of nanoparticles supports reuse, reduce and recycle concept towards the environmental friendly synthesis and also produce the good results compare to chemical methods in some of the cases. MgO nanoparticles can be prepared by solution combustion synthesis using citric acid is a fuel. The same citric acid is available in the nature in so many form just like tamarind, lemon and or...
