Agglomeration of titanium dioxide nanoparticles increases toxicological responses in vitro and in vivo

A toxicologically relevant definition of NM s is therefore not yet available, which affects not only the risk assessment process but also hinders the regulation of nano-products. In this study, we assessed the ...

Is aggregated synthetic amorphous silica toxicologically relevant?

of industrial applications. They are primarily produced as nanosized particles (1–100 nm in diameter) and considered safe as they form large aggregates (> 100 nm) during the production process. So ...

Short-term biodistribution and clearance of intravenously administered silica nanoparticles

takes more time due to hepatic processing and biliary excretion. In treated animals the liver showed in addition a prominent increase of macrophages between both evaluation moments. Within the first 24 ...
