1 Ιουλ 2023 · The TiO 2 NPs have been used in drug delivery and combined cancer treatments due to their ability to reach drug release in cancer cells, their autophagic, photodynamic characteristics, and their non-toxicity up to a concentration of 1 μg mL −1 for normal cells.
It has been reported that the elevated level of oxidative stress by exogenous agents, due to the elevation of ROS in tumor environment, can be more destructive in cancer cells. 41 Prior studies have shown that induction of ROS production in a tumor environment triggers apoptosis, which is the appropriate type of cell death in cancers. 42 Thus ...
27 Οκτ 2020 · Pristine and treated TiO 2 nanoparticles showed comparable acute toxicity and genotoxicity toward HCT116 cells, whereas a small decrease of the induction of oxidative stress after treatment was observed.
26 Ιαν 2021 · The widespread distribution of TiO 2 nanoparticles is released into the air, soil, and/or water throughout and can affect all components of the environment, including humans, animals, and plants on direct exposure to these pollutants . Transfer in food chain usually happens from plants to animals, because plants are a primary food chain source ...
4 Νοε 2021 · In this work, we systematically studied the interactions between three sizes of TiO 2 particles and the cell membrane systems with confocal laser scanning microscopy. We used both giant unilamellar vesicles and human colon cancer cells to mimic actual cell membrane systems.
TiO2 is a compound of great importance due to its remarkable catalytic and distinctive semiconducting properties. ... These materials have also been used to kill bacteria in water treatment 191 and tumor cells in cancer treatment. 14,192 Some reviews are available on the ... organization of the metal and TiO 2 are the factors, which also affect ...
14 Ιαν 2021 · Yet, there have been few studies aimed at determining its direct impact on bacteria, while the available data suggest that TiO 2 NPs may influence microbiota causing problems such as inflammatory bowel disease, obesity, or immunological disorders.
