Sustainable Nanotechnology: Environmental Apps & EHS Implications


Using single particle ICP-MS as a tool for understanding metallonanoparticles transformation during nanotoxicity assays

, , , , , ,
The work presented will establish a method for employing SP-ICP-MS toward the characterization of ENPs following their exposure to a model organism, C. elegans. Sample preparation, SP-ICP-MS analysis, data processing, particulate transport efficiency evaluation, and [...]

Potential artifacts when evaluating the ecotoxicological effects of nanomaterials

, , , , , , , , , ,
Novel physicochemistries of engineered nanomaterials (ENMs) offer considerable commercial potential for new products and processes, but also the possibility of unforeseen and negative consequences upon ENM release into the environment. Investigations of ENM ecotoxicity have [...]

Nano-Safety Science for ensuring safety of nanomaterials ~Biological assessment of silica nanoparticles focused on neutrophil~

, , , , , , , ,
Nanomaterials (NM) with particle sizes below 100 nm display unique properties compared to conventional materials with a submicron size. On the other hand, the debate on safety of NM has expanded worldwide. Therefore, to fully [...]

Zinc Oxide Nanoparticles Induced Apoptosis and Necrosis in Human Neuroblastoma and Astrocytoma Cells

, , , , , , , , , , , , , ,
Because of their escalating uses in industrial and biomedical applications, humans are increasing exposed to nanoparticles in occupational and other environmental settings. However, the environmental safety and health impact of such particles have not been [...]

In Vitro Assessment of Nano-Cerium Oxide (nCeO2) and Nano-Ferric Oxide (nFe2O3) on Fibrogenic and Carcinogenic Potential

, , , , , , , , , , , , ,
Goal of the present study is to investigate the specific cellular responses to nCeO2 and nFe2O3 in various lung cell types and develop an in vitro chronic exposure model to predict the potential fibrogenic and [...]

In vitro Model for Identifying Subchronic Carbon Nanotube Exposure and Lung Cancer Gene Markers

, , , , , , , ,
Concern for increased risk of carbon nanotube-associated lung disease, including carcinogenesis, has been raised due to asbestos-like characteristics. To date, no particle specific nanomaterial exposure or lung cancer markers have been identified. Here, we use [...]

Gaining critical mass: A dose metric conversion study using silver nanoparticles

, , , , , , , , , ,
Mass is still the standard dose metric applied in the nano(eco)toxicology literature. Greater particle surface area or number may be more relevant dose metrics than mass to represent particle interactions with biological surfaces. This investigation [...]
