Impacts of metal and metal oxide nanoparticles on marine organisms

Environmental Pollution, 2014
Increasing use of metal and metal oxide nanoparticles [Me(O)NPs] in products means many will inevitably find their way into marine systems. Their likely fate here is sedimentation following hetero-aggregation with natural organic matter and/or free anions, putting benthic, sediment-dwelling and filter feeding organisms most at risk.

Toxicity of Metal and Metal Oxide Nanoparticles

Metal and metal oxide nanoparticles (NPs) show great promise in biomedical applications, but their toxicity varies. Metallic NPs are stable, while metal oxide and alloy NPs dissolve in biological conditions, releasing metal ions that generate reactive oxygen species (ROS), causing oxidative stress and cellular damage.

Resistivity Sensors of Metal Oxides with Metal Nanoparticles as Catalysts

2016
The metal oxide resistivity sensors are the most common sensors for reducing and oxidizing gases, due to their low cost, easiness of preparation and signal processing. The sensing properties of a metal oxide film depend on the surface roughness, porosity, crystallinity and some other factors, which differentiate for each preparation method.
