Cytotoxicity and photocatalytic activity of Tl doped CeO2 nanoparticles

This paper presents an easy way for the preparation of pure and thallium doped cerium oxide nanoparticles (Tl-CeO2-NP) through of Prosopis fracta. The physicochemical properties of the obtained NP were determined through the PXRD, FESEM/PSA/EDX, UV-Vis/DRS, and Raman analyzing techniques. The FESEM images showed their porous morphology, as well as their altered particle size as a result of being doped of metal. The photocatalytic activity of NP on Methylene blue (MB) dye was tested and observed the higher degradation performance of Tl-CeO2-NP. The toxicity effect of pure and Tl-CeO2-NP on breast cancer cell (MDA-MB-231) line survey by application of MTT test. There were no signs of any cytotoxic on MDA-MB-231 cells throughout finding of NP. In this regard, the performance of a doping process led to the production of non-toxic NP that proved to be applicable for drug delivery purposes and even industrial applications such as dye photodegradation and removal of pollutions.
