Cerium dioxide (CeO2), also known as ceria, is a nanomaterial that has shown potential for use in cancer treatment due to its unique properties. Here are some of the reasons why CeO2 is being investigated for use in cancer treatment:

Overall, CeO2 nanoparticles show promise for use in cancer treatment due to their unique properties, including antioxidant and anti-inflammatory properties, biocompatibility, drug delivery, and imaging capabilities. However, more research is needed to fully understand their potential and to develop safe and effective treatments.

Dear Jotsana,

Many thanks for your interesting question! To the best of my knowledge, CeO2 nanoparticles were discussed as an additive for diesel fuel to reduce the particle concentration in diesel engine exhaust gas. Moreover, Ce4+ is used as a strong oxidiser in analytical chemistry for redox titrations. Finally, many scientific works deal with the cytotoxicity of CeO2 nanoscale particles, e.g.

- Toxicity of CeO2 nanoparticles - the effect of nanoparticle properties

- Redox chemistry of CeO2 nanoparticles in aquatic systems containing Cr(vi)(aq) and Fe2+ ions

- Schwotzer, Daniela (2018): Investigations on the Toxicity of CeO2 Nanoparticles after Subchronic Inhalation of Low Doses. Hannover. Online unter: https://elib.tiho-hannover.de/receive/etd_mods_00000037

You can find some info about nanoparticles used in cancer therapy, e.g. Au, Fe-oxides, HfO2, 177LuPO4, in one of our recent presentations at RG: UV-Emitting Nanoscale Scintillators for Cancer Treatment, April 2022, Infineon University Day

All the best for your research!

Hai Jothsana,

Nano particles(CeO2) are used in cancer treatment because it can absorb and create heat. This heat can be directed to the tumor to destroy the cancer cells while minimizing damage to healthy cells.That's why.

Please read its CeO2 matrix to get an idea.
