Applications of nanoparticles (NP) in medicine, industry and other branches of human activities undoubtedly contribute to technology development and well-being. However, as NP are very small units in a wide range of materials, there is a lack of information related to possible side effects potentially affecting the health of organisms. There is increasing experimental interest in the determinat...

The development of antibacterial coatings is of great interest from both industry and the consumer's point of view. In this study, we characterized tanned leather and polyurethane leatherette, typically employed in the automotive and footwear industries, which were modified by photo-deposition of antibacterial silver nanoparticles (AgNPs). Material surface chemical composition was investigated ...

Titanium dioxide nanoparticles (TiO2 NPs) possess unique characteristics and are widely used in many fields. Numerous in vivo studies, exposing experimental animals to these NPs through systematic administration, have suggested that TiO2 NPs can accumulate in the brain and induce brain dysfunction. Nevertheless, the exact mechanisms underlying the neurotoxicity of TiO2 NPs remain unclear. Howev...

Fast progress in modern nanotechnologies based on use of nanoparticles, nanofibers and nanotubes with different composition, shape size allows elaboration materials superhigh strength, thermal electric conductivity, acoustical optical properties. Those are already widely used industry, transportation, aerospace, marine civil engineering, food processing medicine. Some examples nanoreinforces co...

nanomaterials (nms) are widely used in health and biomedical applications, however, only a few studies investigate their toxic effects.  the present report signifies a contribution to the study of the toxic effects of silver nanoparticles (ag nps)  on   e. coli cells, which is a model organism of anthropogenic pollution. the toxicity of nanoparticles depends on their  chemical and surface prope...

Nano-scale particles have attracted a lot of attention for its potential use in medical studies, in particular for the diagnostic and therapeutic purposes. However, the toxicity and other side effects caused by the undesired interaction between nanoparticles and DNA/RNA are not clear. To address this problem, a model to evaluate the general rules governing how nanoparticles interact with DNA/RN...

One major obstacle for successful application of nanoparticles in medicine is its potential nanotoxicity on the environment and human health. In this study, we evaluated the cytotoxicity effect of dimercaptosuccinic acid-coated iron oxide (DMSA-Fe2O3) using cultured human aortic endothelial cells (HAECs). Our results showed that DMSA-Fe2O3 in the culture medium could be absorbed into HAECs, and...

Fagopyrum esculentum commonly named as buckwheat plant is pseudocereal food crops and healthy herbs but is not known as a bioindicator of environmental condition. In the present study, the effects of ZnO nanoparticles (NPs) and microparticles (MPs) on plant growth, bioaccumulation, and antioxidative enzyme activity in buckwheat were estimated under hydroponic culture. The significant biomass re...
