Background and Aim: Iron oxide nanoparticles are used in fields related to nanotechnology including ecology, magnetic storage, imaging and medicinal purposes. Iron nanoparticles produce reactive oxygen species (Ros). These materials are able to cross the placenta. The aim of this study was to investigate toxic effect of iron oxide nanoparticles on fetal lung in mice. <br ...

UNLABELLED The cellular responses of the J774 macrophage cell line to zinc oxide and zirconium oxide nanoparticles have been studied by a comparative quantitative, protein level based proteomic approach. The most prominent results have been validated by targeted approaches. These approaches have been carried out under culture conditions that stimulate mildly the aryl hydrocarbon receptor, there...

in this work, we report synthesis of superparamagnetic iron oxide nanoparticles at room temperature using microemulsion template phase consisting of cyclohexane, water, cetyltrimethylammonium bromide ctab as cationic surfactant and butanol as a cosurfactant. silica surface modification of the as prepared nanoparticles was performed by adding tetraethoxysilane teos to alkaline medium. the struct...

In this research zinc oxide (ZnO) nano-crystalline powders were prepared by sol-gel method using zinc acetate. The ZnO nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible (UV-Vis), Fourier transform infra-red (FT-IR) and energy dispersive X-ray (EDX) spectroscopy. The structure of nanoparticles was studied using XRD pattern. The c...

a feasibility study on the possible growth of rod-shaped nano size zinc oxide particles on the surface of polyester fabric was investigated. the nanoparticles were produced using a hydrolysis method, with a zinc compound being utilized as the starter material. fourier transform infrared spectroscopy (ft-ir), scanning electron microscopy/energy dispersive x-ray spectrometry (sem/eds) and x-ray d...

in this study, tio2 and zno nanofilms were prepared by sol-gel spin-coating method. nanofilms were characterized by x-ray diffraction (xrd), energy dispersive analysis of      x-ray (edx), scanning electron microscopy (sem) and field emission scanning electron microscopy (fe-esm). structural and morphological properties of nanofilms were investigated. the average crystalline size of tio2 and zn...
