TiO2 Nanomaterials Non-Controlled Contamination Could Be Hazardous for Normal Cells Located in the Field of Radiotherapy.

ABSTRACT: Among nanomaterials (NMs), titanium dioxide (TiO2) is one of the most manufactured NMs and can be found in many consumers' products such as skin care products, textiles and food (as E171 additive). Moreover, due to its most attractive property, a photoactivation upon non-ionizing UVA radiation, TiO2 NMs is widely used as a decontaminating agent. Uncontrolled contaminations by TiO2 NMs during their production (professional exposure) or by using products (consumer exposure) are rather frequent. So far, TiO2 NMs cytotoxicity is still a matter of controversy depending on biological models, types of TiO2 NMs, suspension preparation and biological endpoints. TiO2 NMs photoactivation has been widely described for UV light radiation exposure, it could lead to reactive oxygen species production, kn
