In recent years, fabrication of metal oxide nanoparticles is intensively gaining the interest of various chemists as well as biochemist due to their applications in different fields. Among all the transition metal oxides, CuO and ZnO are the important metal oxide nanoparticles exhibiting tremendous properties and a wide range of applications. Both CuO and ZnO nanoparticles were prepared by comb...

The burden of life on the earth is the source of biological contamination in water. Nanotechnology has promising contributions in control of microbial contaminations and medicinal plants further increase these properties. Presently, copper acetate and nickel oxide nanoparticles were synthesized using 1mM solution of each with Ziziphus mauritiana leaves extract as reducing agent. Nanoparticles w...

the use of an inorganic phase in water-in-oil (w/o) microemulsion   has   received considerable attention recently for preparing metal oxide   nanoparticles. this is a technique, which allows preparation of ultrafine   metal oxide nanoparticles within the size range 40 to 80 nm. preparation of   nano zno and cr 2 o 3 studied, investigated in the inverse   microemulsion system. therefore the nuc...

in this study, zinc oxide nanoparticles (znonps) were synthesized by chemical method and their antibacterial efficiency against a clinical isolate of staphylococcus aureus was studied. the zinc oxide nanoparticles have shown a commendable inhibition effect on the growth of most notorious bacterial pathogen s.aureus. the nanoparticles size and shapes were characterized by transmission electron m...

in this paper, cuo nanoparticles  have been synthesized via solid-state thermal decomposition using copper(ii) schiff base complexes as new precursors at 600ºc under air atmosphere for 3 h. surface morphology of the products were characterized by fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd) and scanning electron microscopy (sem).

in this paper, synthesis of the flower-like zinc oxide was performed using microwave assisted dicationic ionic liquid [mmp(im)2 ]br2 . the polycrystalline flower-like zinc oxide nanostructure was obtained when a suitable mole ratio (ionic liquid /zinc acetate) and short duration microwave was used. x-ray diffraction (xrd), scanning electron microscopy (sem), and photoluminescence (pl) spectra w...

in this study, a mixed matrix polyethersulfone/iron-nickel oxide nanoparticle nanofiltration membrane was prepared by the solution casting technique. polyvinylpyrrolidone was also used as a membrane pore former in membrane fabrication. the effect of iron-nickel oxide nanoparticles concentration in the casting solution on the membrane structure and performance was investigated. scanning optical ...

background & objectives: direct addition of antimicrobial materials to food during food processing is an effective method for controlling microbial contaminants of food and extending the shelf-life of food products. objective of this research was to study the antimicrobial effect of zinc oxide (zno) nanoparticle and potential applications of zno nanoparticles in terms of controling two food...

Aggregation of metal oxide nanoparticles in aqueous media complicates interpretation of in vitro studies of nanoparticle-cell interactions. We used dynamic light scattering to investigate the aggregation dynamics of iron oxide and zinc oxide nanoparticles. Our results show that iron oxide particles aggregate more readily than zinc oxide particles. Pretreatment with serum stabilises iron oxide a...
