Silicon dioxide - Behaviour

The uptake and localization of silicon dioxide particles in cells can be shown by means of electron microscopy.

Histological studies upon intravenous treatment with silicon dioxide (SiO2) nanoparticles have not revealed any damage to the brains of mice.

Silicon dioxide nanoparticles are stable in aqueous solutions compared to other particles which can affect their behaviour, e.g. in sewage treatment plants. In addition, silicon dioxide nanoparticles can bind other (harmful) chemicals already present in the environment.
