Figure 2From: Titanium dioxide nanoparticles induce oxidative stress and DNA-adduct formation but not DNA-breakage in human lung cells BEAS-2B cell exposed to hematite-NP (10 μg/cm2 for 48 h). Agglomerated and single particles were found near the nucleus (1), in the endoplasmic reticulum or lysosomes and surrounded by mitochondria (2). No particles were found within the nucleus or intracellular organelles such as mitochondria or ribosomes. Similarly, also the TiO2-NP were located in the cytosol (mainly in lysosomes) without entering the nucleus.Back to article page
