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.
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.
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.
2 Φεβ 2012 · Introduction. As a bulk material, titanium dioxide (TiO 2) is primarily used as a pigment because of its brightness, high refractive index, and resistance to discoloration. The global production of TiO 2 for all uses is in the millions of tons per year.
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.
24 Αυγ 2018 · Nowadays, TiO 2 is being used frequently for photo degradation of organic molecules and water splitting for hydrogen generation. Most important applications include purification, disinfection of waste water, self-cleaning coatings for buildings in urban areas and the production of the green currency of energy (hydrogen) by splitting water.
1 Ιαν 2023 · Nanoparticle semiconductor photocatalyst like TiO 2 can play a vital role in degrading pollutants for the treatment of water and environment. TiO 2 nanoparticles can absorb radiation the UV region in order to show their photocatalytic properties, but as the UV region is of very less use, by doping with various elements or compounds the band of ...
