MAGNETIC NANOPARTICLESFe3O4 nanoparticles have been widely used as drug carriers, but their toxicity is rarely reported. Herein, we compared the toxicity of novel Fe3O4 nanorings, nanotubes and conventional Fe3O4 nanospheres. The structure, morphology and magnetic properties of Fe3O4 nanoparticles...

Toxicity of nanoparticles (NPs) upon oral exposure has been studied in animals using physiological changes, behavior, histology, and blood analysis for evaluation. The effects recorded include the combination of the action on cells of the exposed animal and the reaction of the microorganisms that pop...
Although nanotoxicology has become a large research field, assessment of cytotoxicity is often reduced to analysis of one cell line only. Cytotoxicity of nanoparticles is complex and should, preferentially, be evaluated in several cell lines with different methods and on multiple nanoparticle batches. ...

Abstract The mitochondrion is a promising target for diagnosis and therapy. Mitochondrial-targeting silica-coated manganese oxide nanoparticles (MnO@SiO2-PPh3+NPs) were successfully synthesized to explore the mitochondrial cytotoxicity of nanoparticles. The mitochondrial targeting property was confirmed by a ...
We are still far from predicting the toxicological profile of new nanoparticles, despite continuous attempts to establish a structure-function relation between the physical and chemical properties of nanoparticles and their interactions with biological systems. Herein, we summarize some basic concept to ...
The production of nanoparticles (NPs) is increasing rapidly for applications in electronics, chemistry, and biology. This interest is due to the very small size of NPs which provides them with many interesting properties such as rapid diffusion, high specific surface areas, reactivity in liquid or...
Cytotoxicity of ZnO Nanoparticles Can Be Tailored Cytotoxicity of ZnO Nanoparticles Can Be Tailored by Modifying Their Surface Structure: A Green Chemistry Approach for Safer Nanomaterials 期刊名称: ACS Sustainable Chemistry & Engineering 作者: Punnoose, Alex,Dodge, Kelsey,Rasmussen, John W.,Chess, ...
To add an additional layer of complexity, there appears to be a difference in species sensitivity, with the pig being more sensitive than the rat, particularly following the administration of nanoparticles (Szebeni et al., 2007, 2012). Dezsi et al., (2014) goes on to speculate that the ...
