In the ongoing search for practical uses of rare-earth metal nanoparticles, cerium dioxide nanoparticles (nanoceria) have received special attention. The purpose this research was to study biomedical effects nanocrystalline forms oxide obtained by different synthesis schemes and evaluate effect concentrations nanoceria (from 10−2 10−6 M) on cells involved in regeneration skin cell structures su...

We report a novel non-enzymatic nanocatalyst based approach to construct an electrochemical aptasensor involving the synergistic contribution of a nanoceria (nCe) tag and graphene oxide (GO). The aptamer was immobilized on the surface of a GO modified electrode. The target analyte was captured by the immobilized aptamer via a specific competitive mechanism between the free and the nCe labeled t...
