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.
3 Ιουν 2021 · Herein, the response of lipopolysaccharide-truncated Escherichia coli K12 mutants to TiO 2 nanoparticles (TiO 2 NPs, exposure in dark) is addressed at the molecular, single cell, and...
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.
Titanium dioxide (TiO 2) is a naturally occurring metal oxide and is one of the five engineered nanomaterials most commonly used in daily consumer products, including food 1.The TiO 2 food additive, referred to as E171 in the European Union (EU), is commonly used as a whitening and brightening agent in confectionary (candies and chewing gum), white sauces and icing 1, 2, 3.
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.
TiO 2 nanostructures—due to the high biocompatibility, tunable drug releasing ability and low toxicity—are recognized as an appropriate candidate to increase the clinical therapeutic effect of conventional chemotherapeutic agents through targeted delivery and controlled release.
