Analysis of the Characteristics and Cytotoxicity of Titanium Dioxide Nanomateri...
Bettencourt, Ana; Gonçalves, L.; Gramacho, A.; Vieira, A; Rolo, D.; Martins, Carla; Assunção, Ricardo; Alvito, Paula; Silva, Maria JoãoSeveral metallic nanomaterials (NMs), such as titanium dioxide nanomaterials (TiO2), present beneficial properties with a broad range of innovative applications. The human population is exposed to TiO2, particularly by ingestion, due to its increasing use as a food additive and inclusion in dietary supplements and food packaging materials. Whether this oral exposure may lead to adverse local or systemic outcome...
Applicability of the harmonized in vitro digestion method to titanium dioxide n...
Alvito, Paula; Assunção, Ricardo; Gramacho, A.; Silva, M.J.; Louro, H.; Martins, C.Titanium dioxide nanomaterials (TiO2 NMs) have a high potential for ingestion by human populations, due to their increasing use as food additives, inclusion in dietary supplements and food packaging materials. Whether this oral exposure may lead to adverse local or systemic outcomes, has been the subject of research. In vitro studies have generated contradictory results, possibly due to differences in the physi...
Nanomaterials in foods and the standardized static in vitro digestion method: c...
Martins, Carla; Assunção, Ricardo; Gramacho, A.; Alvito, Paula; Silva, Maria João; Louro, H.The use of nanoparticles (e.g. titanium dioxide) in commercial food products to modify some properties, such as brightness and whiteness, increased in the last years and is nowadays widespread. Despite the inhalation of nanoparticles is already a topic of concern, the potential adverse health effects due to ingestion still presents gaps of knowledge. In fact, gastrointestinal tract is the first interface betwee...
