Cerium Oxide Nanoparticles Improve Lifespan of Stored Blood

Cerium oxide nanoparticles in cancer

With the development of many nanomedicines designed for tumor therapy, the diverse abilities of cerium oxide nanoparticles (CONPs) have encouraged researchers to pursue CONPs as a therapeutic agent to treat cancer. Research data have shown CONPs to be toxic to cancer cells, to inhibit invasion, and to sensitize cancer cells to radiation therapy and chemotherapy. CONPs also display minimal toxic...

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 oxidative stress and that the neuroprotection is independent...

Cerium oxide nanoparticles (CeO2 NPs) improve the developmental competence of in vitro-matured prepubertal ovine oocytes.

The present study investigated whether supplementation with different doses of cerium dioxide nanoparticles (CeO2 NPs) during in vitro maturation (IVM) of prepubertal ovine oocytes influenced their embryonic development in vitro. Cumulus-oocyte complexes derived from the ovaries of slaughtered prepubertal sheep underwent IVM with CeO2NPs (0, 44, 88 or 220µg mL-1). Matured oocytes were fertilise...

Enhanced chemiluminescence detection of thrombin based on cerium oxide nanoparticles.

Polyacrylic acid coated nanoceria (PNCs) were found to greatly enhance the chemiluminescence (CL) intensity of the luminol-H(2)O(2) system, and by virtue of the catalytic ability of PNCs, a sensitive and specific sandwich assay for human α-thrombin was developed.
