4 Νοε 2021 · The results demonstrate the strong effect of particle size on membrane disruption and leakage behaviors, especially indicating the cytotoxicity of nano-sized TiO 2 particles improved with decrease of particle sizes. Therefore, the use of TiO 2 NPs as a food additive has potential health risks.
18 Ιαν 2012 · This study quantifies the amount of titanium in common food products, derives estimates of human exposure to dietary (nano-) TiO 2, and discusses the impact of the nanoscale fraction of TiO 2 entering the environment. The foods with the highest content of TiO 2 included candies, sweets, and chewing gums.
Importantly, the use of a SOD corona or surface passivated TiO2 nanoparticles prevents the decrease of HDAC9. These expts. elucidate the underlying mechanism of TiO2 nanoparticle-mediated cellular responses including oxidative stress and changes in gene expression.
Titanium dioxide nanoparticles (TiO2NPs) are among the key nanoparticles (NPs) that have gained extensive practical use and can be synthesized through a wide range of physical, chemical, and green approaches.
27 Οκτ 2020 · Abstract. Background: Oral exposure to titanium dioxide (TiO 2) is common since it is widely used in food and pharmaceutical products. Concern on the safety of this substance has been recently raised, due to the presence of an ultrafine fraction in food-grade TiO 2.
26 Ιαν 2021 · Hydroxyl radicals (OH) are associated with titanium dioxide (TiO2) nanoparticle-induced cytotoxicity and oxidative DNA damage in fish cells. Mutation Research, Fundamental and Molecular Mechanisms of Mutagenesis.
11 Φεβ 2024 · TiO 2 nanoparticles of different shapes, sizes, and crystal structures have been synthesized, which can be used as food additives or incorporated into food packaging materials to improve their antibacterial and physical properties.
