In situ soft X-ray absorption spectroscopy (XAS) was employed to study the adsorption and dissociation of carbon monoxide molecules on cobalt nanoparticles with sizes ranging from 4 to 15 nm. The majority of CO molecules adsorb molecularly on the surface of the nanoparticles, but some undergo dissociative adsorption, leading to oxide species on the surface of the nanoparticles. We found that th...
Nanoparticles O C TO B ER 2 01 2 The potential level of exposure to dust of manufactured nanoparticles varies considerably depending on the type of nanoparticle powder handled in the production. Addition of nanoparticles to paint, lacquer and plaster may change the amount of dust particles generated during sanding of these materials. In contrast, the particle-size distribution of the sanding du...
BACKGROUND Luminescent rare-earth-based nanoparticles have been increasingly used in nanomedicine due to their excellent physicochemical properties, such as biomedical imaging agents, drug carriers, and biomarkers. However, biological safety of the rare-earth-based nanomedicine is of great significance for future development in practical applications. In particular, biological effects of rare-e...
Nanobiotechnology has provided promising novel diagnostic and therapeutic strategies which capable to create a broad spectrum of nano-based imaging agents and medicines for human administrations. Several studies have demonstrated that the surface of nanomaterials is immediately coated with suspended proteins after contact with plasma or other biological fluids to form protein corona-nanoparticl...
Background: due to widespread applications of nanoparticles in biomedicine and biotechnology and their effects on human health, the present study was conducted to determine the cytotoxic effect of CuO nanoparticles on serum biochemical parameters and liver histopathological changes of NMRI mice. Methods: In this experimental study, forty two female NMRI mice were randomly divided into six group...
Exposure to nanoparticles by various routes results in size-dependent translocation of the systemic circulation and subsequent accumulation liver. The purpose this study was determine possible adverse effects liver long-lasting nanoparticle presence organ. Mice exposed a single dose (162 µg/animal equivalent 9 mg/kg body weight) TiO2, CeO2 or carbon black intratracheal instillation intravenous ...
Due to its ability in chemical oxidation of contaminants, iron nanoparticle is a material of choice to remove lead ions from aquatic solutions. In this study a reduction method in solution phase was applied to synthesize thenanoparticles. Afterwards, the size of the synthesized particles were confirmed by Scanning Electron Microscopy. It is worth noting that th...
This project is focused on understanding the optoelectronic properties of silicon nanoparticles produced by nonthermal silane plasmas. In situ FTIRis capable of distinguishing surface hydride coverage of silicon nanoparticles and is a prominent technique used to study the surface chemistry of nanoparticles during exposure to plasma environments. Ex situ photoluminescence,UV-vis, SEM, RBS, XRD, ...
Today, there is an increasing interest in the use of metal nanoparticles in health sciences. Amongst all nanoparticles, the gold nanoparticles have been known to kill the cancer cells under hyperthermic condition by near-infrared frequency electromagnetic waves. On the other hand, although there are different physiochemical methods for disinfection of microbial pollution, however applications o...
