After inhalation platinum nanoparticles behave similar to particles of the same size but from other materials or ultrafine dust. Compared to really toxic materials platinum nanoparticles induce a very small biological effect.

 

Rights Studies with rats and mice did not show toxic effects of platinum nanoparticles after inhalation when compared to black carbon or ultrafine dust particles [1]. A very small fraction of the inhaled particles could be found in the liver indicating that these very small particles (Ø 18 nm) can penetrate through the lung tissue into the bloodstream and are then transported to the liver.
