Nanocrystalline ceria: Synthesis, structure-sensitive properties, and promising applications
Directed search for further manifestations of size-dependent effects in the functional properties of nanomaterials constitutes a key line of nanotechnologies research. The major size-dependent effects were analyzed for nanocrystalline ceria. The practically significant techniques for preparation of ceria nanopowders with controllable micromorphology were analyzed. Selected promising applications of this material were described.

Protection from radiation-induced pneumonitis using cerium oxide nanoparticles
In an effort to combat the harmful effects of radiation exposure, we propose that rare-earth cerium oxide nanoparticles (free-radical scavengers) protect normal tissue from radiation-induced damage. Preliminary studies suggest that these nanoparticles may be a therapeutic regenerative nanomedicine that will scavenge reactive oxygen species, which are responsible for radiation induced cell damage. The effectiveness of [...]
Cerium and yttrium oxide nanoparticles are neuroprotective
The responses of cells exposed to nanoparticles have been studied with regard to toxicity, but very little attention has been paid to the possibility that some types of particles can protect cells from various forms of lethal stress. It is shown here that nanoparticles composed of cerium oxide or yttrium oxide protect nerve cells from [...]
Synthesis of Biocompatible Dextran-Coated Nanoceria with pH-Dependent Antioxidant Properties
Biocompatible dextran-coated nanoceria (cerium oxide nanoparticles) are found to exhibit excellent, pH-dependent antioxidant properties. They provide cytoprotection from free radicals to normal cells but not to cancer cells, and thus have potential applications in antioxidant and anti-inflammatory coatings for prosthetic devices and tissue engineering and in improved cancer therapeutics.
