Some food products will include titanium dioxide on their nutrition label. But again, it can be hard to tell for those who don't list the ingredient.
In a 2016 study published in Scientifica (Cairo), Egyptian researchers examined the effects of titanium dioxide nanoparticles on the organs of mice by orally administering the food additive daily, for five days. The results showed that the exposure produced “mild to moderate changes in the cytoarchitecture of brain tissue in a time dependent manner.” Furthermore, “Comet assay revealed the apoptotic DNA fragmentation, while PCR-SSCP pattern and direct sequencing showed point mutation of Presenilin 1 gene at exon 5, gene linked to inherited forms of Alzheimer’s disease.” The researchers wrote: “From these findings, “the present study concluded that TiO2NPs is genotoxic and mutagenic to brain tissue which in turn might lead to Alzheimer’s disease incidence.”
4. Solar Cells The photovoltaic industry is another critical area where anatase TiO2 is making an impact. As a semiconductor, it plays a role in dye-sensitized solar cells (DSSCs), providing a pathway for improving energy conversion efficiency in sustainable energy solutions.
