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.
3 Ιουν 2021 · TiO 2 NPs operate as membrane strippers, which induce osmotic stress, inactivate cell osmoregulation and initiate lipid peroxidation, which ultimately leads to genesis of membrane vesicles....
25 Φεβ 2022 · TiO 2 has a wide range of applications including as photocatalysts, in solar cells, self-cleaning surfaces, wastewater treatment and as an antimicrobial agent.
1 Μαρ 2022 · Plant proteins interact with TiO 2 nanoparticles in food matrices to form biocoronas. • These biocorona can be divided into ‘hard’ and ‘soft’ layers. • Hydrogen bonds play an important role in biocorona formation. • Protein adsorption/desorption depended on surface properties of the nanoparticles. •
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 ...
