Titanium dioxide nanoparticles (TiO<sub>2</sub> NPs), used as pigments and photocatalysts, are ubiquitous in our daily lives. Previous work has observed cellular oxidative stress in response to the UV-excitation of photocatalytic TiO<sub>2</sub> NPs. In comparison, most human exposure to TiO<sub>2</sub> NPs takes place in the dark, in the lung following inhalation or in the gut following consumption of TiO<sub>2</sub> NP food pigment. Our spectroscopic characterization shows that both photocatal ...[more]
