abstract：:Single-walled carbon nanotubes (SWCNTs) are widely used in industrial and medical sectors, and the increasing exposure of SWCNTs necessitates the studies of their potential environmental and health effects. Considerable efforts have been made to improve the dispersion of SWCNTs by chemical modifications. However, the ...

abstract：:With the advent of nanoparticles produced in high quantities and employed in products or processes, the need to evaluate their potential toxicological effects is necessary. For this purpose, biopersistence studies are needed to assess the possible effects of nanoparticles in parallel with a proper characterization. Th...

abstract：:Abstract Nickel, zinc, and copper oxide nanoparticles (NiONP, ZnONP, and CuONP) and their aqueous extracts (AEs) were applied to A549 lung epithelial cells to determine the cytotoxicity, IL-8 production, and activation of transcription factors. Nanoparticles (NPs) and their AEs were also instilled into rat lungs to ...

abstract：:Six TiO₂ and two CeO₂ nanomaterials with dry sizes ranging from 6-410 nm were tested for their ability to cause DNA centered free radicals in vitro in the concentration range of 10-3,000 ug/ml. All eight of the nanomaterials significantly increased the adduction of the spin trap agent 5,5-dimethyl-1-pyroline N-oxide (...

abstract：:There is a paucity of data regarding the safety of administering solid gold nanoparticles (AuNPs) in large animal tumor models. We assessed the acute toxicity and biodistribution of 5 nm and 25 nm solid AuNPs in New Zealand White rabbits (n = 6 in each) with implanted liver Vx2 tumors 24 h after intravenous injection....

abstract：:The use of imaging tools to probe nanoparticle-cell interactions will be crucial to elucidating the mechanisms of nanoparticle-induced toxicity. Of particular interest are mechanisms associated with cell penetration, translocation and subsequent accumulation inside the cell, or in cellular compartments. The objective ...

abstract：:Despite the wide use of silver nanoparticles (nano Ag), its toxicity still remains poorly understood. In this report, nano Ag induced an increase in platelet aggregation and procoagulant activation which are the key contributors to thrombotic diseases. In freshly isolated human platelets, nano Ag induced platelet aggr...

abstract：:Cadmium (Cd) is a component in quantum dot 705 (QD705). Whether QD705 behaves similar to Cd in vivo is of great concern. We compared the distributional kinetics of cadmium chloride (CdCl(2)) and QD705 in mice after intravenous injection. QD705 showed a longer plasma and body retention than CdCl(2) and could be detecte...
