Abstract: Cerium dioxide is a unique material which is promising for biomedical applications. The vast majority of currently existing methods of synthesis results in CeO$_2$ formation in the form of nanopowders. However such powders are useless as biomedical preparations because their exact dosage is nearly impossible. In this paper, we have offered a facile method of ceria stable sols synthesis and investigated the effect of varying concentrations and molar ratio of initial reagents on the CeO$_2$ particle size. The toxicity of ceria sols has been analyzed using Vibrio fischeri and Escheriсhia Coli bioluminescent microorganisms. Comparative studies of photocatalytic activity of ceria sols has been also performed.
Keywords: cerium dioxide, sols, biological activity, photocatalytic activity.
